    Abstract:
    Three operated cases of lobar intracerebral hemorrhage (LICH) related to cerebral amyloid angiopathy (CAA) were studied clinicopathologically. They constituted about 8% of all LICH cases (n = 37) operated upon in our institute (DUSM) during the past 3 years. Case 1, 2 and 3 aged 71, 67 and 73 years, respectively. There were 2 males (Cases 1 & 2) and 1 female (Case 3). Only one case (Case 3) had both hypertension and dementia before hemorrhage. In all 3 cases, neurologic symptoms deteriorated after admission. The hematoma involved the right temporo-parietal in 1 (Case 1), the right parieto-occipital in 1 (Case 2) and the left fronto-parietal region in 1 (Case 3). Case 1 developed a new hematoma in the right occipital lobe on the day following surgery. On CT, the hematoma was multilobular in shape and located very superficially extending to the subarachnoid space in all cases. There was no abnormal enhancement in and around the hematoma upon contrast infusion. Angiography showed only an avascular mass sign in case. At surgery, the hematoma was extruded onto the cortical surface in all cases. The surgical outcome was good in 2 (Cases 1 & 2) and fair in 1 (Case 3). Removed hematomas, solid nodular tissues and adjacent brain tissues were examined histologically using hematoxylin and eosin, Azan-Mallory, elastica van Gieson, silver and Congo red stains. Arteries in the hematoma wall, the subarachnoid space and the adjacent brain parenchyma were intensely stained with Congo red and showed birefringence on polarized light.(ABSTRACT TRUNCATED AT 250 WORDS)
