 There are numerous foci of susceptibility effect throughout the supratentorial and infratentorial brain. The largest of these lies along the posterior aspect of the midbrain/pons measuring 16 mm AP x 20 mm transverse x 22 mm craniocaudal (as measured on T2 sequences). The majority of these are T2 hypointense, with a few demonstrating central T1/T2 hyperintensity. None demonstrate perilesional edema nor associated development of venous anomaly. Note is made of a small, fat-containing focus within the right parietal/occipital bone, presumably representing hemangioma. There are other subtle and very faint foci of suspected enhancement involving the calvarium, again suggestive of hemangiomas.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no midline shift. The pituitary gland is normal in size. There is no evidence for acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Mucosal thickening is present within right frontal sinuses, bilateral ethmoid air cells (right greater than left) and left mastoid air cells. There is no abnormal enhancement within the brain.
