Generate impression based on findings. | Radiculopathy, cervical region [M54.12], Reason for Study: ^Reason: eval for radiculopathy, myelopathy History: neck pain and left sided radicular pain There is straightening of cervical spine. The cranial-cervical junction is normal. There is minimal fluid collections on the atlanto axial joint indicating inflammatory changes including osteoarthritic changes. There is no evidence of atlanto axial subluxation.The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The cord signal is normal. Degenerative changes are specified by the intervertebral level as follows: C2-C3: disc dessication, no neuroforaminal narrowing or spinal stenosis. C3-C4: disc dessication, no neuroforaminal narrowing or spinal stenosis. C4-C5: there is broad based central to left disc protrusion which abuts thecal sac, no neuroforaminal narrowing or spinal stenosis.

Generate impression based on findings. | Multiple sclerosis. Worsening gait. Evaluate for progression. Numerous juxtacortical and periventricular T2 hyperintense lesions are seen in both cerebral hemispheres becoming nearly confluent in the periatrial regions and along the temporal horns. Lesions are also evident within the pons, along the margins of the fourth ventricle, and in the cerebellum. There is questionable elevated T2 signal within the dorsal spinal cord at the C2 level, but this is equivocal and not adequately assessed on the present examination.The immediate prior examination was obtained with significantly different imaging technique which complicates precise comparison. However, given this caveat, no definite or significant interval changes are seen. When comparison is made to the older examination from 2013, most of the lesions show no significant interval change, but at least one lesion in the left centrum semiovale has become less conspicuous.No evidence of significant parenchymal edema or mass effect is seen. No abnormal extra-axial fluid collections are detected. The ventricular system remains within normal limits for size and morphology. Multiple nonspecific subcentimeter right parotid nodules are evident. | A substantial burden of supratentorial and infratentorial white matter lesions is again demonstrated compatible with the history of multiple sclerosis. Although the immediate prior examination was obtained with different imaging technique which complicates precise comparison, no definite or significant interval changes are appreciated.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report. |
Generate impression based on findings. | Clinical question: Please evaluate for. Signs and symptoms: Headaches, lethargy and on anticoagulant Nonenhanced CT of brain: Examination demonstrates a large area of low-attenuation primarily in the subcortical white matter of right posterior frontal -- parietal with atrophic changes of overlapping cortex. This finding could represent an ischemic stroke however the appearance may also be secondary to edema from malignancy. There is no definitive mass effect with the above finding and to exclude other possibilities an MRI examination is recommended. There is no evidence of hemorrhage, mass effect, midline shift or hydrocephalus. | 1.Area of low-attenuation in the subcortical white matter of right posterior frontal could represent an old stroke however to exclude possibility of an underlying malignancy MRI examination is recommended.2.There is no evidence of intracranial hemorrhage midline shift or hydrocephalus. |
Generate impression based on findings. | 41 year old female with right shoulder pain. Evaluate for labral tear. Evaluation is slightly limited due to the inability to properly position the patient.ROTATOR CUFF: There is mild increased signal intensity of the supraspinatus and infraspinatus tendons, suggesting mild tendinosis. Additionally, gadolinium appears to undercut the articular surface fibers of the rotator cuff at its insertion, in particular, the posterior fibers of the supraspinatus and anterior fibers of the infraspinatus. This may represent partial thickness stripping of the articular surface fibers from the bone, however, there is no full-thickness rotator cuff tear. There is perhaps mild undersurface fraying of the subscapularis tendon. We see no evidence to suggest a full-thickness tear.SUPRASPINATUS OUTLET: There is perhaps a trace amount of fluid within the subacromial subdeltoid bursa, but we see no evidence of frank bursitis. Intra-articular gadolinium does not enter the subacromial subdeltoid bursa. Mild osteoarthritis affects the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate osteoarthritis affects the glenohumeral joint with thinning of the articular cartilage of the glenoid, particularly along its anterior and superior aspect with a full-thickness articular cartilage cleft identified. Gadolinium enters the superior labrum, indicating a SLAP tear, which does not definitively extend to involve the tendon of the long head of the biceps. The anterior superior labrum appears at least partially detached from the glenoid which may represent extension of the labral tear. There is fraying of the anterior inferior glenoid labrum.BICEPS TENDON: There is a small focus of low signal intensity within the tendon sheath which may represent a loose body, but the tendon of the long head of the biceps is otherwise normal. | 1. SLAP tear as described above with additional tearing/fraying of the anterior glenoid labrum.2. Moderate osteoarthritis affects the glenohumeral joint.3.

Generate impression based on findings. | Hemangioma of intracranial structures [228.02], Reason for Study: ^Reason: possible pontine infarct History: pt not waking up Brain MRIInterval near total excision of the left tegmentum cavernous malformation. While the area of susceptibility effect at the resection bed is slightly larger than the original resected cavernous malformation (measuring 14 mm in transverse now compared to 11 mm previously), this does not been certainly reflect actual expansion especially given the lack of significant change in the minimal rightward deviation of the aqueduct of Sylvius. Just anterior to the area of susceptibility effect related to the resection bed of the cavernous malformation, there is a focal diffusion restriction on the left side of midbrain anterior to aqueduct and extends anteriorly to the region of the mesial aspect of the left side red nucleus and just proximal to the left substantia nigra (series 400, image 13/32). These findings are associated with edema in the midbrain which is new compared to the baseline examinationThere is also linear tract-like susceptibility abnormality in the posterior aspect of the left superior/mid temporal lobe which was not present on the preoperative images and therefore most likely procedure related. Cervical MR angiography: 3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The right vertebral artery is small throughout its course, most probably congential. Otherwise, there is normal flow enhancement through the bilateral common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries. Cranial MR Venography:3D MRV brain post-gadolinium with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus. The inferior sagittal sinus is not visualized but this was not changed since the baseline examination and is likely a normal variation of very small or absent inferior sagittal sinus.Cervical spine MRI:The cranial-cervical junction is normal. There is straightening of the normal cervical lordosis which may reflect patient position. The cervical spine alignment is otherwise anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal narrowing or myelopathy. The intervertebral discs are notable mild loss T2 intensity and height at C5-C6 which is associated with disc-osteophyte complex mildly narrowing the spinal canal but not touching or displacing the cord. The height and T2 signal are preserved at the other discs. The paraspinal soft tissues are notable for mild edema surrounding the intubated airway which is nonspecific.Degenerative changes are specified by the intervertebral level as follows: C2-C3: no neuroforaminal narrowing or spinal stenosis. C3-C4: no neuroforaminal narrowing or spinal stenosis. C4-C5: no neuroforaminal narrowing or spinal stenosis. C5-C6: Shallow disc-osteophyte complex is slightly more prominent on the right and causes mild spinal canal narrowing. Uncovertebral proliferative changes slightly more pronounced on the left causing minimal left neural foraminal narrowing. C6-C7: no neuroforaminal narrowing or spinal stenosis. C7-T1: no neuroforaminal narrowing or spinal stenosis. | 1.Blood products at the resected cavernous malformation in the mid brain tegmentum is likely to be residual blood products of the cavernous malformation. 2.New edema has developed around the resection bed along with small focus of diffusion restriction which may represent tiny midbrain infarct.3.Hemorrhagic tract is present in the posterior superior left temporal lobe and most likely procedure related as described above.4.Right frontal ventriculostomy has been placed with its tip near the right foramen of Monro. Ventricle size is stable.5.The cranial and cervical MR angiography as well as cranial MR venography show no significant abnormalities.6.Cervical spine shows mild degenerative C5-C6 osteophyte complex but no significant spinal canal or foraminal narrowing.Dr. Monther Qandeel discussed the above findings over the phone with the Neuro ICU resident Dr. Robin a.

Generate impression based on findings. | Stabbing right-sided headache, worse in life. Assess for vascular dissection or subarachnoid hemorrhage. The study is limited by patient motion. Also, immediately following gadolinium injection, the patient reported warm sensation in her chest and significant nausea. The examination was halted. Symptoms resolved within 2 minutes without treatment but no postcontrast images were obtained for the MRA of the neck or MRV of the cranium.MRI BRAIN WITHOUT CONTRAST:The brain demonstrates normal morphology and signal characteristics. There is no space-occupying lesion, midline shift or brain herniation. The ventricles and the other CSF-containing spaces are normal accounting for predominantly CSF filled sella, compatible with partially empty sella. There is no abnormal diffusion restriction or susceptibility effect to indicate acute stroke or intracranial hemorrhage.There is no gross orbital abnormality. There is no destructive skull lesion. Thickening of the subcutaneous fat along the scalp likely relates to patient body habitus. There is mild prominence of the optic nerve sheath although remaining within normal limits. No definite posterior scleral flattening is identified.CRANIAL MR VENOGRAPHY WITHOUT AND WITH CONTRAST:As discussed above, no postcontrast MR venography was performed. Motion also limits the examination.There is no sign of significant dural venous thromboses on the noncontrast MR venography. Attenuation of the flow-related signal at the junction of the transverse and sigmoid sinuses is a common imaging finding of no clinical significance.CRANIAL MR ANGIOGRAPHY WITHOUT CONTRAST:Flow-related signal in the intracranial internal carotid arteries and the paired anterior and middle cerebral arteries and their major branches is preserved as well as the vessel caliber. Similarly, the vertebrobasilar system shows no significant stenosis or aneurysm.NECK MR ANGIOGRAPHY WITHOUT AND WITH CONTRAST:As discussed above, only noncontrast enhanced images are available. There is bilateral attenuation of flow-related signal in the carotid bulbs which likely relates to turbulent flow. Otherwise, the cervical carotid arteries show preserved flow-related signal and caliber. Similarly, the cervical vertebral arteries are also preserved except for suboptimal visualization of the origin of the left vertebral artery which may reflect technical limitation of noncontrast enhanced cervical MR angiography. Aortic arch branching pattern is conventional.The fat saturated precontrast axial images of the neck show no sign of intramural hematoma/vessel dissection. There is asymmetric enlargement and lobulation of thyroid gland, more pronounced on the left, probably reflecting the presence of thyroid nodules. | 1.The examination is limited as described above because of inability to complete the examination following the contrast injection as well as patient motion throughout the remainder of the examination.2.There is no definitive intracranial abnormality.3.There is no definite cervical or intracranial artery stenosis accounting for the above described limitations. There is also no sign of vessel dissection.4.No gross evidence dural venous thrombosis.5.Partially empty sella is nonspecific and may represent a normal variant. However, given the incidental note of increased fat within the scalp suggestive of patient's body habitus, as well as history of headaches and relatively young age, clinical correlation should be made for idiopathic intracranial hypertension.6.Asymmetric thyroid gland enlargement and lobulation probably reflect multinodular goiter. |

Generate impression based on findings. | 14-year-old male with posterior thigh mass in the pain. There is a large mass centered within the popliteal fossa of the knee, surrounding the popliteal artery and vein as well as the tibial nerve. The mass extends approximately 10 cm above the knee joint superiorly, abutting the posterior cortex of the distal femur, the medial aspect of the biceps femoris, and the posterolateral aspect of the vastus medialis. There appears to be a thin fat plane between the mass and the distal semimembranosus. At the level of the knee joint, the bulk of the mass is situated between the heads of the gastrocnemius with a small "tail" extending along the anterior margin of the lateral head of the gastrocnemius and additional tissue entering the posterior aspect of the intercondylar notch. The mass does appear to focally invade the medial head of the gastrocnemius, with streaky elements also invading the lateral head of the gastrocnemius along its length distally. Overall the craniocaudal dimension is at least 30 cm with a cross-sectional diameter of up to 6 cm. The mass also abuts the soleus and popliteus muscles. The mass has a lobulated appearance with some focal fatty septa within the mass, but it is predominantly isointense to muscle on T1-weighted images and is predominantly hyperintense on T2-weighted images, with near-fluid signal intensity. The mass enhances in a predominantly peripheral and septal distribution with a more nodular component of enhancement along the posterior aspect at the level of the distal femur. Poorly defined infiltrative enhancement is noted as the mass extends into the lateral head of the gastrocnemius.The menisci are intact and the articular cartilage appears normal. The anterior and posterior cruciate ligaments are intact as are the medial collateral ligament and lateral collateral ligament complex. The extensor mechanism is intact. The bone marrow signal is within normal limits. | Large lobulated mass centered in the popliteal fossa of the knee as described above. Based on its morphology and signal characteristics, the mass may represent a lymphatic malformation. Given its intimate association with the popliteal vessels, extremely extensive cystic adventitial disease is considered a possibility, albeit less likely. The high signal intensity of the mass on T2WI with what appear to be fatty components raise the possibility of a myxoliposarcoma, although the fatty components may simply represent entrapped fat within the lobules of the tumor. Synovial sarcoma may also have a predominantly cystic appearance, although the mass surrounds the neurovascular bundles rather than displacing them, which would be atypical for most malignancies. Follow-up with orthopedic oncology is recommended. |

ABDOMEN: Several of the imaging sequences are degraded by respiratory motion and wrap around artifact.LIVER, BILIARY TRACT: Diffuse hepatic steatosis. Significant hepatomegaly measuring 29 cm in craniocaudal dimension. Otherwise the liver is normal in morphology. No intrahepatic or extrahepatic biliary ductal dilatation. No filling defect in the common bile duct. Normally distended gallbladder.SPLEEN: Status post splenectomy.PANCREAS: Postsurgical changes from distal pancreatectomy. No evidence of residual or recurrent tumor.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Ventral subcutaneous postsurgical changes.OTHER: No significant abnormality noted. | Hepatomegaly with diffuse steatosis.

Generate impression based on findings. | Pseudotumor, on Cytoxan, follow up. Compared to 11/13/2014, subcentimeter thick dural-based enhancing lesion measuring 6 to 8 mm in the coronal plane underlying the left parietal craniotomy flap has not significantly changed in size. There is unchanged encephalomalacia involving the left paracentral lobule. No new mass or edema. No significant mass effect. No hydrocephalus. Stenosis involving the anterior and mid superior sagittal sinus is better assessed on prior MRV. There is no evidence of acute infarct. There are postoperative findings related to right mastoidectomy with unchanged enhancement. Ectopic cerebellar tonsils again seen. | 1. No significant change in dural thickening along the left parietal convexity compatible with known pseudotumor. Unchanged encephalomalacia involving the left frontoparietal lobes. No new mass or mass-effect.2. Unchanged postoperative appearance of the right mastoid cavity. |
