ipsilateral cerebral blood flow (CBF) above the metabolic demands of the brain tissue following repair of unilateral carotid stenosis (1). The patient with hyperperfusion may rarely develop the hyperperfusion syndrome, including severe ipsilateral headache, face and eye pain, seizures, and intracerebral hemorrhage (1-3), which is a rare but devastating complication after carotid endarterectomy ...

BACKGROUND AND PURPOSE It has been speculated that the same type of hypertensive small-artery disease can cause either intracerebral hemorrhages or ischemic lesions, depending on the circumstances. METHODS To test this hypothesis, we examined the association between spontaneous intracerebral hematomas and both small chronic hemorrhages and ischemic lesions using echo planar and T2-weighted MR...

Cavernous malformations (CMs), characterized by the presence of a hemosiderin rim and intralesional hemorrhage, are relatively common intracranial vascular malformations. Extralesional hemorrhages arising from CMs are seen in a minority of cases, but most of them show typical CM findings on magnetic resonance imaging. Here, the authors report two cases of pathologically confirmed CM presenting ...

The incidence of intracerebral hemorrhage over 13 years is compared between two Hisayama cohorts. Among men aged 40 years or older, the annual incidence declined significantly from 3.1/1,000 in the early cohort (1961-1970) to 1.2/1,000 in the recent cohort (1974-1983). Massive ganglionic hemorrhage decreased, while small or medium-sized intracerebral hemorrhage increased in the recent cohort on...

Intracerebral abscess formation as a late sequela to ischemic stroke is a rare entity. Intracerebral abscess is a life-threatening affliction with a significant mortality rate necessitating prompt diagnosis and treatment. We present the case of a 67-yearold female with cerebral ischemic infarction complicated forty weeks later by an intracerebral abscess. The diagnosis was only reached after re...

Pheochromocytoma is a rare cause of hypertension in children. Hypertension is one of the common reasons of posterior reversible encephalopathy. Intracerebral hemorrhage is a serious and unexpected complication of hypertensive encephalopathy due to pheochromocytoma, and very rarely seen in the childhood. Intracerebral hemorrhages should be searched if there are hypertensive reversible signal cha...
