Medullary thyroid carcinoma on clinical trial, history of pneumothorax, follow up examination for assessment of response CHEST:LUNGS AND PLEURA: There are persistent, widespread bilateral pulmonary micronodules, predominantly confluent. The reference conglomerate identified from the prior study has not significantly changed, measuring 35 x 25 mm on coronal image 28/57 ( 28 x 36 mm previous).The left pneumothorax has slightly increased, appearing to have further retracted from the chest wall.MEDIASTINUM AND HILA: The reference right paratracheal node currently measures 8 x 13 mm on image 34/153 (14 x 9 mm on previous). The right thyroid lesion (6/153) and right jugular lymphadenopathy (5/153) are unchanged.Stable calcified left hilar nodes. The heart size remains normal, without pericardial effusion.CHEST WALL: Multiple small sclerotic foci within the lumbar spine and mixed sclerotic and lytic lesion in the vertebral body of T1 are stable.Of particular note, there is a paucity of subcutaneous fat.ABDOMEN:LIVER, BILIARY TRACT: There is arterially enhancing lesion measuring 9 x 9 mm at the capsule of the posterior segment of the right hepatic lobe (84/153). This extends beyond the hepatic contour and is concerning for metastasis rather than hemangioma. The previous described low density, ill-defined lesion is again noted in the posterior hepatic lobe (81/153), also suspicious for metastasis.SPLEEN: No significant abnormality notedKIDNEYS, URETERS: No significant abnormality notedADRENAL GLANDS: No significant abnormality notedPANCREAS: There is prominence of the pancreatic head which currently measures 34 mm in AP dimension on image 124/153. As compared to 26 mm on the prior study. Therefore, this raises question of enlarging conglomerate of peripancreatic lymph nodes or metastatic involvement with the pancreatic head. Further evaluation of this and of the hepatic lesions may be obtained with a dedicated MRI or triphasic CT abdomen.No intraperitoneal ascites appreciated.BOWEL, MESENTERY: No significant abnormality noted.
1. Metastatic thyroid carcinoma, predominantly stable.2. Arterially enhancing lesion in posterior hepatic lobe. Enlarging soft tissue density in the region of the pancreatic head.

77-year-old female. Right shoulder pain. ROTATOR CUFF: Thickening and increased signal intensity of the supraspinatus tendon indicating moderate tendinosis. The articular surface fibers are slightly indistinct, which may reflect undersurface fraying. Fluid signal intensity within the anterior aspect of the tendon at its insertion on the greater tuberosity indicates an interstitial tear that involves the majority of the thickness of the tendon and is under just 1 cm in AP dimension. We suspect that this is a concealed tear, but a small amount of fluid in the adjacent subdeltoid bursa raises the possibility of a small tear of the adjacent bursal surface fibers. The supraspinatus muscle appears normal. The tendinosis extends posteriorly to involve the anterior fibers of the infraspinatus, but we see no definite infraspinatus tendon tear. The infraspinatus muscle is intact. The muscle and tendon of the teres minor and subscapularis are intact.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint with spurring of the anterior aspect of the acromion. There is a small amount of fluid in the subacromial/subdeltoid bursa. A lobulated collection of fluid signal intensity along the posterolateral aspect of the humeral head at the infraspinatus insertion may reflect a loculated fluid in the subdeltoid bursa or a small cyst.GLENOHUMERAL JOINT AND GLENOID LABRUM: Small glenohumeral joint effusion. Alignment of the glenohumeral joint is anatomic. There is increased signal intensity within the anterior labrum suggestive of degeneration; the labrum otherwise appears normal considering the patient's age. Small cysts in the greater tuberosity anteriorly likely reflect overlying rotator cuff pathology. Small cysts posteriorly in the humeral head may not be of any clinical significance.BICEPS TENDON: Increased signal intensity within the long head of the biceps tendon suggests mild tendinosis. Fluid within the biceps tendon sheath may simply reflect extension of fluid from the glenohumeral joint.ADDITIONAL
Moderate tendinosis of the supraspinatus and infraspinatus with partial thickness insertional tearing of the anterior fibers of the supraspinatus tendon and other findings, as described above.

Gait abnormality, paresthesias. There are multiple foci of T2/FLAIR hyperintensity in the bilateral subcortical and periventricular white matter. Lesions include one adjacent to the right temporal horn as well as involving the lateral aspect of the middle cerebellar peduncle on the left including the nerve root entry zone of the left trigeminal nerve. Susceptibility effect noted in the left lateral middle cerebellar peduncle and along the lateral pons on the left. Few ovoid lesions perpendicular to the ventricle are also seen. Small focus of susceptibility measuring 4 mm is seen involving the right posterior frontal lobe, compatible with chronic microhemorrhage.No restricted diffusion to suggest acute ischemia. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Brain parenchyma is otherwise unremarkable for age. Major flow-voids are preserved. Sella and orbits are grossly within normal limits. Mild mucosal thickening in the paranasal sinuses and small maxillary mucous retention cysts are seen . Bone marrow signal and extracranial soft tissues are within normal limits.
1. Multiple T2/FLAIR hyperintense white matter lesions including few which are ovoid and perpendicular to the lateral ventricles, one lesion adjacent to the right temporal horn, as well as one involving the left lateral aspect of the middle cerebellar peduncle on the left adjacent to the trigeminal nerve root entry zone. Appearance and distribution of these lesions is suggestive although not diagnostic of demyelinating disease.2. 4 mm focus of susceptibility effect in the right posterior frontal lobe as well as multiple foci along the left pons and left middle cerebellar peduncle compatible with chronic microhemorrhages. Left middle cerebellar peduncle/left trigeminal nerve root entry zone lesion described in #1 is in itself suggestive of chronic demyelination; however the presence of chronic hemorrhage would be unusual. As such, superimposed chronic small vessel ischemic disease with chronic hemorrhage including the left pons should also be considered.

1.Since the prior exam there does not appear to be any significant change. There is redemonstration of multiple microhemorrhages within the subcortical white matter of the supratentorial brain bilaterally but predominantly in the right hemisphere and also in the left cerebellar hemisphere. This asymmetry is of uncertain significance.2.There appears to be hemosiderin deposition along the left precentral sulcus which was also identified on the prior exam and most likely indicates that prior subarachnoid blood was present at this location.3.Periventricular and subcortical white matter lesions of a mild degree are nonspecific. At this age they are most likely vascular related. 4.There is a stable 7 mm calcified extra-axial lesion present adjacent to the right postcentral sulcus most likely represent a burnt out meningioma.

The risks (including, but not limited to, those of bleeding, infection, allergic reaction, temporary nerve block, pain, and inability to access the joint) and benefits of the procedure were explained to the patient, and informed written consent was obtained. A pre-procedural “time-out” form was completed.The patient was placed supine on the fluoroscopy table. The left knee was localized fluoroscopically, and a spot radiograph was obtained. The skin was cleansed and covered with a sterile drape. The skin and subcutaneous tissues were anesthetized with 1% lidocaine using a 25-gauge needle.Under fluoroscopic guidance, a 22-gauge needle was advanced into the joint. Attempted aspiration yielded no fluid. Next, 20 ml of a 50/50 mixture of Omnipaque 240 (to confirm the intra-articular position of the needle) and dilute Multihance (0.1 cc in a 10 cc vial of saline, for subsequent MR imaging) were injected into the joint. Contrast opacified the joint in the expected manner. A spot radiograph was obtained for documentation. The needle was withdrawn. Blood loss was negligible (<1cc), and patient tolerated the procedure well without immediate complication. An adhesive bandage was placed on the patient’s skin. Routine post procedure instructions were communicated to the patient. The patient was escorted to the MRI suite for further imaging in stable condition. Please refer to the subsequent MRI report for further information.Exposure time: 30 seconds.

Malignant neoplasm of pelvis [C76.3] / Personal history of antineoplastic chemotherapy [Z92.21], Reason for Study: ^Reason: history of sacral teratoma (recurrent), treated with resection, chemotherapy and radiation. History: worsening back pain Subtle enhancing areas of the soft tissue at the level of lower sacral area indicating postoperative scar changes which are not completely included with current scan. In addition, comparing to outside MRI scan performed on July 2, 2016, the low signal intensity lesion around the left obturator foramen is not covered either.Therefore, this scan needs to be repeated without additional charge for complete evaluation of the postoperative status of sacrococcygeal lesion (known as teratoma).For the purpose of this dictation, the vertebral body demonstrates costochondral junction is labeled T12. Inhomogeneous MR signal intensities of sacrum and bilateral iliac bones may represent post radiation changes. There is no evidence of associated soft tissue mass. There is normal lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. 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. The conus medullaris terminates at the T12-L1 level. There is no evidence of abnormal enhancement, cord compression or mass. Degenerative changes are specified by the intervertebral level as follows: T12-L1: no neuroforaminal narrowing or spinal stenosis. L1-L2: no neuroforaminal narrowing or spinal stenosis. 10mm sized vertebral body hemangioma is seen. L2-L3: no neuroforaminal narrowing or spinal stenosis. L3-L4: no neuroforaminal narrowing or spinal stenosis. L4-L5: no neuroforaminal narrowing or spinal stenosis. L5-S1: Minimal bulging of disc, disc dessication.

Female, 66 years old, altered mental status and history of epilepsy.Additional history obtained from the electronic medical record: PMHx of epilepsy (partial complex seizures), previous R MCA ischemic stroke with L side weakness with residual deficit, presenting with encephalopathy and dysarthria over the last 2 days. MRI brain: There are extensive patchy areas of restricted diffusion, compatible with acute infarct in the right anterior inferior frontal lobe, right superior frontal lobe, left posterior frontal lobe and left anterior parietal lobe, including the lateral left pre and post central gyri. There is T2/FLAIR signal abnormality in these regions. Additionally, there is high T1 signal in the anterior frontal lobe gyri, which may be related to petechial hemorrhage or mineralization. There is no large intraparenchymal hemorrhage.Large areas of encephalomalacia are redemonstrated in the right frontal and parietal lobes, as well as the right caudate and periventricular white matter, which is again compatible with chronic infarct. Associated ex vacuo dilatation of the right lateral ventricle is again noted. The ventricles are stable in size. There is evidence of chronic hemosiderin staining in the region of right frontal lobe infarct. Wallerian degeneration of the right cerebral peduncle is also again noted. Small chronic infarcts are redemonstrated in the right cerebellar hemisphere and right paramedian pons.Moderate abnormal T2/hyperintense signal in the periventricular and subcortical white matter is a non-specific finding which most commonly represents age-indeterminate small vessel ischemic disease. There is no extra-axial fluid collection, midline shift or herniation. No gross intracranial mass is identified. The major vascular intracranial flow voids are preserved at the skull base, compatible with gross patency. The paranasal sinuses and mastoid air cells are grossly clear.MRA neck: Postcontrast MRA images are nondiagnostic due to patient motion and difficulty with bolus delivery. A noncontrast time-of-flight MRA sequence was attempted. This, however, is also corrected by artifact and not reliable for interpretation.
1. Findings compatible with acute infarcts in the bilateral frontal lobes and left anterior parietal lobe. Suggestion of petechial hemorrhage or cortical laminar necrosis in the right frontal infarct region without gross hemorrhagic conversion. 2. Large chronic infarcts in the right cerebral hemisphere and multiple small infarcts in the right cerebellar hemisphere and pons are redemonstrated.3. Nondiagnostic MRA of the neck.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.

Female, 59 days old, with sepsis due to group B streptococcus, assess for abscess or structural abnormality. Presumed meningitis. Corrected gestational age of approximately 36 weeks. Relatively symmetric extensive gyriform T1 and T2 hyperintensity is seen involving the bilateral occipital and temporal lobes with associated diffusion restriction in the occipital lobes. The region demonstrates patchy susceptibility compatible with blood product. Evidence of developing encephalomalacia is also seen, particularly in both occipital lobes and the anterior left temporal lobe.Extra-axial presumably subdural hemorrhage is evident along the anterior lateral right temporal lobe measuring up to 6 mm in thickness. Bilateral subdural hemorrhages are also evident along the cerebellar hemispheres. The sigmoid sinus flow voids are evident but the transverse sinus flow voids are not well seen. Along the right cerebral hemisphere, a subdural hematoma is noted measuring up to 5 mm in thickness with T1 and T2 hyperattenuating material layering dependently.A 10 mm parenchymal hemorrhage is evident at the left caudothalamic groove. Hemorrhage extends from here into the left frontal horn. A small amount of hemorrhage is also evident at the level of the foramen of Magendie. There may be some hemorrhage layering within the occipital horns versus purulent material.Cystic encephalomalacia is seen within the left frontal lobe. The brain parenchyma is generally T2 hyperintense which may represent a combination of edema and immature myelination. Hemosiderin staining is seen along the choroid plexi.On postcontrast imaging, sulcal vascularity is noted, but there are no discretely rim-enhancing fluid collections.
1.Abnormal gyriform signal is seen within the occipital and temporal lobes with evidence of restricted diffusion in the occipital lobes. Some but not all of this parenchyma demonstrates susceptibility indicating the presence of blood product . Findings possibly represent a combination of ischemic injury with some laminar necrosis and superimposed hemorrhagic staining. The presence of purulent material could also potentially contribute to these findings.2.Evidence of developing encephalomalacia is seen in both occipital lobes and the anterior left temporal lobe. Cystic encephalomalacia is present in the left frontal lobe.3.Subdural fluid collections are present along the right lateral temporal lobe and along the right cerebral hemisphere. Blood product is seen layering along the cerebellar hemispheres adjacent to the transverse sinuses. The transverse sinus flow voids are not well visualized which could represent obscuration or compression from adjacent blood product. However, the possibility of sinus thrombosis or occlusion cannot be excluded.4.A germinal matrix hemorrhage is demonstrated on the left with intraventricular extension. Blood product is seen within the left frontal horn, and at the foramen of Magendie. Blood product and/or purulent material may also be present layering within the occipital horns. 5.Most or all of the above findings can be accounted for by a combination of prematurity and intracranial infection. No definite rim-enhancing collections are seen to suggest abscess.

History of 3+4 adenocarcinoma in the left lateral apex. Patient used prophylactic antibiotics before and after the procedure asprescribed. The patient received antibiotic prophylaxis with oral Ciprofloxacin 500 mg bidstarting the night before the procedure. He took 2 tablets of Ciprofloxacin 500 mg beforethe procedure and will take two tablets after the procedure. Following the discussion ofthe risks, benefits, and alternatives of the procedure with the patient, informed consent was obtained forthe procedure. The procedure was performed under moderate conscious sedation.MRI focus in the left apex peripheral zone suspicious for patient's known cancer waslocalized with T2 weighted MR images. Following sterile preparation, Visualase laserablation template was placed on the patient's perineum and localized on MR images andregistered to the MR images where prostate lesion could be visualized.Following local anesthesia with lidocaine, 14-gauge MR- compatible needles were insertedinto the left side of the prostate. Upon confirmation of the tip of the needle on theside close to the known lesion, laser ablation in the left apex was performed with15-W, 90 % power. This was repeated several times to adequately ablate the left apex peripheral zone. The patient tolerated the procedure well without any immediate complications.Pre-and postcontrast axial MR images are obtained before and after administration of 14 ccMultiHance, upon completion of the procedure. On MR images of ablation defect was notedwithin and around the apical peripheral zone.COMPLICATIONS: None.
