Primary intracerebral hemorrhage due to probable cerebral amyloid angiopathy complicated by brain abscess: case report

Cerebral amyloid angiopathy (CAA), in which deposition of amyloid within the arterial media and adventitia is the remarkable feature, causes spontaneous lober cerebral hemorrhage in elderly person, and some reports show the quite high occurrence rate of this entity among intracerebral hemorrhage in patents above 70 years old. Brain abscess resulting from intracerebral hemorrhage is rare. To our knowledge, no report of such hemorrhage which is caused by CAA has been published so far. We report a case of brain abscess, from which Stenotrophomonas maltophilia was isolated, following spontaneous non-hypertensive intracerebral hemorrhage caused by probable CAA, with a review of the relevant literature.
