Generate impression based on findings. | Reason: low back and buttock pain and Lt leg pain for 3-4 weeks History: as above Evaluation is limited by patient motion artifact. Evaluation of the hamstring tendon origins is limited due to patient motion artifact, however, the proximal end of the conjoined tendon on the left is indistinct and may be avulsed from the ischium. The semimembranosus tendon appears intact at its origin. The sacrotuberous ligament likewise appears intact. There is a small quantity of fluid situated between the ischium and hamstring tendons which could reflect the sequela of a hamstring tear or a bursitis. There is a small amount of fluid and enhancement also noted tracking posteriorly and laterally supporting a bursitis. The relatively mild nature of the edema adjacent to the hamstring tendons suggests that this process may be chronic in etiology. There is mild edema and enhancement between the ischium and lesser trochanter on the left which may represent inflammation due to the aforementioned process or potentially a ischiofemoral impingement, although the ischiofemoral interval does not appear particularly narrowed. There is also a small amount of fluid adjacent to the right hamstring tendons at their origin that may represent a combination of partial-thickness tearing and a bursitis. Mild peritrochanteric edema and enhancement on the left is not necessarily of any current clinical significance. The bone marrow signal intensity of the pelvis and proximal femora is normal. Please refer to the lumbar spine MRI report regarding the degenerative changes of the lumbar spine. There is a small amount of fluid within the right hip, but no frank joint effusion. | 1. Limited examination due to patient motion artifact. There is fluid adjacent to the hamstring tendons at their origin, left greater than right, which likely represents a combination of bursitis and partial-thickness tearing with possible avulsion of the left conjoined tendon from the left ischium. We are uncertain, however, if these findings, which may be chronic, are responsible for the patient's pain.2. Degenerative disc disease of the lumbar spine. Please refer to the dedicated MRI lumbar spine report for additional details. |

Generate impression based on findings. | Hereditary ataxia, unspecified [G11.9] / Other symptoms and signs involving the musculoskeletal system [R29.898], Reason for Study: ^Reason: scan ataxia AND acute leg weakness L History: ataxia; mild left leg weakness Brain MRINo evidence of acute ischemic or hemorrhagic lesion.There are gyriform susceptibility artifacts following bilateral frontal lobe around the area of frontal sinuses. This could represent artifacts from the frontal sinus air but also can represent prior subarachnoid space blood.There are evidence of encephalomalacia on bilateral frontal gyrus rectus, mesial and lateral orbital gyri (left worse than right) most likely represent prior traumatic contusion.Disproportional diffuse cerebellar volume loss is seen without definitive evidence of pontine volume loss. The ventricles, sulci and cisterns are symmetric and unremarkable.

Generate impression based on findings. | Leukodystrophy and epilepsy. Assess progression of brain involvement. Bilateral subdural effusions over the cerebral convexities have increased in size mildly. They have a maximum thickness of 13 mm on the right and 11 mm on left, compared to 6 mm and 8 mm previously. As before, the fluid is T2 bright, similar to CSF, and T1 hyperintense to CSF. The underlying prominent subarachnoid spaces as well as the ventricles are slightly smaller than previously though remain abnormally enlarged. There is no susceptibility effect in either the subdural or subarachnoid spaces. The confluent, T1-hypointense, T2/FLAIR-hyperintense signal involving the deep and periventricular cerebral white-matter is slightly less prominent. However, this apparent improvement may reflect evolution of the white-matter injury and white matter volume loss rather than an improvement in the disease process. There continues to be signal abnormality in the subinsular white-matter but relative sparing of the subcortical U fibers otherwise. T2-hyperintensity along the corticospinal tracts extending into the posterior aspect of the posterior limb of the internal capsules is unchanged. There is also abnormal T2-hyperintensity in the corpus callosum. Striated T2-hyperintensity in the pons is unchanged. Confluent T2-hyperintensity involving the deep cerebellar white-matter has slightly increased since the previous examination.Brain parenchymal volume loss continues to be symmetric other than being slightly more pronounced in the frontal and temporal lobes. The degree of volume loss has perhaps slightly increased from the prior examination.There is mild, smooth dural contrast enhancement and thickening, likely reactive to the effusions. There is no abnormal intracranial contrast enhancement otherwise. No acute infarct is seen. There is no mass or mass-effect. The major cerebral flow voids are intact. The posterior pituitary bright spot is absent. The orbits, skull, and scalp soft tissues are grossly unremarkable. Fluid signal is present posterior ethmoid and right maxillary sinuses as well as the mastoid air cells. There are also secretions in the posterior aspect of the pharynx along nasogastric and endotracheal tubes. | 1.Since the previous examination of November 2015, there has been evolution of the brain parenchymal (predominantly white-matter) injury. Though the cerebral T2-hyperintense white-matter lesions appear less prominent and less discrete, associated volume loss is suspected to have mildly progressed since the previous examination. At the same time, the cerebellar white-matter T2-hyperintense abnormality has mildly increased. 2.The bilateral cerebral convexity subdural collections have slightly increased in size, which may reflect passive dilatation due to progressive underlying brain volume loss. The lack of susceptibility effect within the collections suggests that they may represent nonhemorrhagic effusions, though chronic subdural hematoma remains in the differential. |

The medial facet of the femoral trochlea appears slightly hypoplastic suggesting mild dysplasia. |
Generate impression based on findings. | Liver lesion and complex renal cyst noted on screening ultrasound. 53-year-old male with chronic hepatitis B. ABDOMEN:LIVER, BILIARY TRACT: The right hepatic lobe lesion seen on the prior ultrasound is not definitely identified. An 8 mm T2 hyperintense lesion in the posterior right hepatic lobe (segment 6/7) appears to be a separate incidentally detected lesion based on size and location. This lesion demonstrates faint arterial enhancement with progressive enhancement on the hepatic, portal venous, and delayed phases, likely representing an hemangioma. Additional subcentimeter subcapsular cysts noted. The background liver is non-cirrhotic in appearance.Gallbladder adenomyomatosis noted.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: 18 mm cyst in the left kidney lower pole, seen on the prior ultrasound, without associated soft tissue or enhancement. The left midpole calculus seen on prior ultrasound is not definitively seen on MRI, likely due to spatial resolution/slice thickness. Punctate nonenhancing T2 hyperintense foci in the right kidney are too small to characterize though likely also represent cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted. | 1. Right hepatic lobe lesion seen on the prior ultrasound is not definitely identified. 2. Subcentimeter posterior right hepatic lobe lesion likely representing an hemangioma. 3. Left renal cyst without suspicious features. |
Generate impression based on findings. | Female, 82 years old, with facial droop and slurred speech. No restricted diffusion is seen. Mild scattered white matter T2 hyperintensity is seen. No edema or mass effect is detected. There is no acute intracranial hemorrhage or any abnormal extra-axial fluid. The ventricles and sulci are prominent compatible with likely age-related volume loss. | 1.No acute intracranial abnormality.2.Mild chronic small vessel ischemic disease. |
