Abstract
Alzheimer's disease and cerebral amyloid angiopathy (CAA) are often associated. Amyloid accumulation within leptomeningeal and small/median-sized cerebral blood vessels in CAA results in vessel fragility, leading to spontaneous leptomeningeal bleeding, lobar intracerebral hemorrhage (ICH) and cerebral microbleeds. CAA is also associated with non-traumatic subdural hematoma. The role of CAA-related vessel fragility in hemorrhagic complications after trauma, brain surgery, and intracranial drain insertion in CAA is unknown. We present two sporadic CAA patients with intracranial drain-related ICH, probably due to different underlying mechanisms, related to indirect and direct CAA-associated vessel fragility.
