Intracerebral hemorrhage (ICH) is common among various types of storkes; however, it is rare in young patients and patients who do not have any risk factors. In such cases, ICH is generally caused by vascular malformations, tumors, vasculitis, or drug abuse. Basal ganglia ICH is rarely related with distal lenticulostriate artery (LSA) aneurysm. Since the 1960s, a total of 29 distal LSA aneurysm cases causing ICH have been reported in the English literature. Despite of the small number of cases, various treatment methods have been attempted : surgical clipping, endovascular treatment, conservative treatment, superficial temporal artery-middle cerebral artery anastomosis, and gamma-knife radiosurgery. Here, we report two additional cases and review the literature. Thereupon, we discerned that young patients with deep ICH are in need of conventional cerebral angiography. Moreover, initial conservative treatment with follow-up cerebral angiography might be a good treatment option except for cases with a large amount of hematoma that necessitates emergency evacuation. If the LSA aneurysm still persists or enlarges on follow-up angiography, it should be treated surgically or endovascularly.

A ruptured distal lenticulostriate artery (LSA) aneurysm is detected occasionally in moyamoya disease (MMD) patients presented with intracerebral hemorrhage. If the aneurysm is detected in hemorrhage site on angiographic evaluation, its obliteration could be considered, because it rebleeds frequently, and is associated with poorer outcome and mortality in MMD related hemorrhage. In this case report, the authors present two MMD cases with ruptured distal LSA aneurysm treated by endovascular embolization.

Bilateral traumatic hemorrhage of the basal ganglia is an extremely rare neuropathologic entity. This report describes a 50year-old man with bilateral basal ganglia hemorrhage with occipital fracture of the skull after head trauma. The mechanism of development of traumatic hemorrhage of the basal ganglia has been not clear. But, it is presumed to be secondary to rupture of the lenticulostriate or anterior choroidal artery by shearing as a result of acceleration/deceleration forces. We briefly summarize our uncommon case and discuss its possible mechanisms.
