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.
海绵窦内动脉瘤罕见，约占颅内动脉瘤的3%。由于这种动脉瘤体积会逐渐增大并引发各种神经症状，因此需要进行鉴别诊断。在本报告中，分析了7例海绵窦内动脉瘤病例。总之，大多数病例出现动眼神经或展神经麻痹。虽然很多病例疑似三叉神经麻痹，但实际上仅1例出现该症状。大多数病例发展缓慢且呈进行性。1例表现为急性起病，需要与颈内动脉-后交通动脉瘤进行鉴别诊断。对于海绵窦内动脉瘤的诊断，计算机断层扫描非常有价值。
