In the elderly population, amyloid angiopathy is associated with cerebral infarcts as well as<unk>  in superficial locations, rather than deep white matter or basal ganglia. These are usually described as "lobar". These bleedings are not associated with systemic amyloidosis.<unk> c neoplasms are more complex, heterogeneous bleeds often with associated edema.

Glioblastomas are the most common primary malignancies to<unk>  while thyroid, renal cell carcinoma, melanoma, and lung cancer are the most common causes of<unk>  from metastatic disease. Other causes of<unk>  include<unk> c transformation of infarction which is usually in a classic vascular distribution and is seen in approximately 24 to 48 hours following the ischemic event. This<unk>  rarely extends into the ventricular system.
