The authors encountered 300 cases of intracranial aneurysm in the past 10 years. Among them a giant intracranial aneurysm was present in 15 cases (5%). The giant aneurysm was located in the internal carotid artery in 11 cases, anterior communicating artery in 1 case, middle cerebral artery in 1 case, and basilar artery in 2 cases. Its symptoms were cavernous syndrome in 9 cases, and bleeding from the nose, hydrocephalus and paresis of lower cranial nerves each in 1 case. It was incidentally discovered in 2 cases, while manifesting itself with subarachnoid hemorrhage only in 1 case. Direct operation (clipping) was done wherever it was feasible, with 3 cases treated so far by this method. The next best surgical procedures were ST-MC anastomosis + internal carotid ligation, these were done in 3 cases, and common carotid ligation was performed in 4 cases. In cases treated by non-surgical mean, death due to rupture oc-curred in as many as 3 cases. CT scan performed an important role in dignosis. Histopathologic findings suggested that an intracranial aneurysm gradually enlarges to attain a huge size through repeated clot-formation within aneurysm, organization of the clot and fresh bleeding into aneurysm.
