[Analysis of 7 cases with intracavernous aneurysm]

Intracavernous sinus aneurysm is rare and consists of approximately 3% of intracranial aneurysm. Since this aneurysm increases gradually in size and causes various neurological signs, differential diagnosis is necessary. In this report, seven cases of intracavernous sinus aneurysm were analyzed. In conclusion, oculomotor or abducens nerve palsy were seen in most cases. Though trigeminal nerve palsy was suspected in many cases, it was actually seen only in one case. Most cases developed slowly and progressively. One case showed an acute onset and the differential diagnosis from internal carotid-posterior communicating aneurysm was needed. To diagnose intracavernous sinus aneurysm, computed tomography scan was very valuable.
