Brain abscess associated with cerebral amyloid angiopathy and hemorrhage.

PURPOSE
We want to report an extremely rare condition, brain abscess associated with cerebral amylid angiopathy and hemorrhage.


CASE REPORT
We report on a 64-year-old woman who presented initially with moderate fever and headache. She was initially misdiagnosed with a bleeding tumor or arteriovenous malformation rupture and treated without antibiotic therapy. The mass was surgically drained due to neurological deterioration on day 14 after admission. Streptococcus virdians was isolated from the pus culture. The pathology evaluation showed cerebral amyloid angiopathy. She received intravenous antibiotic therapy for 4 weeks. She was eventually discharged home with left quadrantanopia.


CONCLUSION
This case reminds us early recognition of brain abscess formation at the site of intracerebral hemorrhage is very important for prompt and appropriate treatment to improve the overall prognosis.
