Reason: Evaluate for abnormality; history of synovial sarcoma of the thigh. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are a few small foci of increased T2 signal within the periventricular and subcortical white matter without enhancement, susceptibility or diffusion restriction. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are mildly enlarged and may reflect some volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits and skull are grossly unremarkable. There is a focal prominence of fat in the subcutaneous tissues overlying the right parietal calvarium which may represent a small lipoma. Mild mucosal thickening of the bilateral sphenoid and maxillary sinuses. There is fluid within the mastoid air cells bilaterally.
1.No evidence of intracranial metastases.2.A few subcortical and periventricular T2 hyperintense foci without diffusion restriction or enhancement are nonspecific. Differential includes migraine headaches, small vessel ischemic disease, demyelinating diseases and other infectious/inflammatory etiologies.3.Fluid in the mastoid air cells bilaterally.4.Mild volume loss, more than would be expected considering patient's age.
