Clinical History: Headaches. Facial, neck, and right arm spasm for 5 days.
Brain MRI with and without intravenous contrast. 6 cc of Gadavist were administered intravenously.
FINDINGS: There is a linear focus of abnormal T2 hyperintensity within the left cerebellum. There is minimal
superimposed SWAN signal loss in this area suggesting chronic microscopic hemorrhage at the site of a remote insult.
There is no intra-axial or extra-axial mass or fluid collection. There are a few scattered punctate and small nodular foci
of periventricular and subcortical white matter FLAIR and T2 hyperintensity in both hemispheres. There is no definite
focus of signal abnormality within the corpus callosum or brainstem. There is no definite abnormal focus of parenchymal
or meningeal enhancement. There is normal enhancement of the major dural venous sinuses. There is normal
enhancement of the major arteries at the skull base. There is no acute intraorbital abnormality or gross orbital
asymmetry. There is is postsurgical changes involving the paranasal sinuses without an air-fluid level. There are multiple
small sharply circumscribed scalp lesions. These are nonspecific. Clinical correlation is recommended
