 There are at least 5 punctate to small foci of susceptibility hypointensity within the supratentorial brain, as well as a punctate focus in the right pons. The largest of these is present within the anterior left temporal lobe measuring 9 mm AP x 11 mm transverse x 11 mm craniocaudal dimension (as measured on T2 sequences). None demonstrate perilesional edema. There are no associated developmental venous anomalies.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or 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. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
There are at least 5 punctate to small foci of susceptibility hypointensity within the supratentorial brain, as well as a punctate focus in the right pons, consistent with the provided history of familial cerebral cavernous malformations. The largest of these is present within the anterior left temporal lobe measuring 9 mm AP x 11 mm transverse x 11 mm craniocaudal dimension (as measured on T2 sequences). None demonstrate perilesional edema. There are no associated developmental venous anomalies.
