Аннотация:A 33-year-old male was admitted unconscious. Computerized tomography scan disclosed an intracerebral hematoma with ventricular penetration. Angiography demonstrated the characteristic appearance of moyamoya disease as well as aneurysms in the peripheral portion of the lenticulostriate artery. The patient died of re-rupture of the aneurysms fourteen days after the onset. At autopsy, these aneurysms proved to be true aneurysms. Possible hemodynamic mechanisms of cerebral aneurysms associated with moyamoya disease are discussed.
