Most of "so-called" posterior communicating @entity438 previously reported, originated from the internal carotid-posterior communicating junction. @entity439 arising from the posterior communicating artery itself are very rare. The @entity2896 caused by @entity438 is also very rare. We are reporting a case with the @entity439 arising directly from the distal half of the posterior communicating artery presenting the @entity2896 . This 73-year-old @entity1 who had no treatment with @entity101 for several years was admitted for sudden onset of severe @entity10 , @entity391 and unconsciousness on @entity3490 , 1984. She opened her eyes when addressed and had disorientation, @entity322 , @entity1269 and @entity2896 . A 4-vessel angiography revealed the @entity439 originating directly from the distal half of the posterior communicating artery. The @entity1 underwent left-frontotemporal craniotomy on the 27th day after @entity510 under Hunt _ Kosnic Grade 3. The @entity439 originated directly from the distal half of the posterior communicating artery and directed inferior-posterior-laterally below the oculomotor nerve. The neck was successfully clipped. Immediate post-operative course was uneventful until the 7th day after surgery. On the 8th day she had hypertensive @entity548 and expired. The autopsy could not be obtained. The saccular "true" posterior communicating @entity438 with isolated unilateral @entity2896 as seen in our case has not been reported. Considering the operative findings, we thought the aneurysmal dome contacted directly with the abducens nerve.
