Amyloid angiopathy-related cerebellar hemorrhage.

BACKGROUND

The posterior fossa localization of amyloid angiopathy-related hemorrhage is very unusual. Less than 10 cases have been previously reported. Surgical management of amyloid angiopathy-related hemorrhage is the subject of controversy.

RESULTS

Typical aspects of amyloid angiopathy were found within the surgically removed biopsies of 71-year-old nonhypertensive, nondemented woman suffering cerebellar hemorrhage.

CONCLUSIONS

Amyloid angiopathy-related hemorrhage could occur in the cerebellum, and diagnosis might be suspected when no past history of mental deterioration and/or arterial hypertension are present and when angiography rules out vascular malformation. Surgical management seems to have the same restricted indications as in other brain areas.
