We report two cases of distal cerebral aneurysms that were treated by parent artery occlusion with short Guglielmi detachable coils (GDCs). One patient had a presumed mycotic aneurysm of the distal left posterior cerebral artery, and the other had a partially clipped aneurysm of the distal right anterior inferior cerebellar artery that had hemorrhaged. Short GDCs allow controlled, accurate occl...

Akinetic mutism is described in various clinical presentations but typically is defined as a state wherein the patient appears awake but does not move or speak. It can be divided into two different subtypes; the most common subtypes depend on the lesion location, mesencephalic-diencephalic region, also called apathetic akinetic mutism (somnolent mutism), and those involving the anterior cingula...

A case with infarction in the territory of the anterior choroidal artery (AChA) due to embolic occlusion of the internal carotid artery (ICA) is rare. We described two cases and investigated the mechanism of the territory of the AChA. Case 1 was a 69-year-old man. Case 2 was a 71-year-old woman. The neurological examination in both cases showed left homonymous hemianopsia, left facial palsy, le...

A hypertensive 69-year-old man presented with an incidentally discovered non-ruptured aneurysm of the persistent primitive olfactory artery (POA). The POA originates at the terminal portion of the internal carotid artery, runs along the olfactory tract anteriorly toward the crista galli, and forms an acute angle with the distal anterior cerebral artery. The aneurysm was located at this characte...

During the period from January 1975 to December 1988, a total of 28 among 215 cases or 13.0% with multiple aneurysms were seen in the Department of Neurosurgery, Hiroshima University. Classifying by sex, there were 17 males and 11 females with a mean age of 52 years. The number of aneurysms was four in 2 cases, three in 6 cases, and two in 20 cases. By location, there were 13 aneurysms in the a...

PURPOSE To measure mean blood flow in individual cerebral arteries (carotid, basilar, anterior cerebral, middle cerebral, and posterior cerebral) using a cine phase contrast MR pulse sequence. METHODS Ten healthy volunteers (22 to 38 years of age) were studied. The cine phase-contrast section was positioned perpendicular to the vessel of interest using oblique scanning planes. This pulse sequ...
