Arachnoid cysts and intracranial aneurysms are not rare, but it is unusual for an aneurysm to be associated with an arachnoid cyst. The objective of this study was to reveal the association between arachnoid cysts and intracranial aneurysms.
Methods included to report 3 cases with these 2 pathologies and to perform a systematic review of the English and Japanese literature using PubMed, Scopus, and Ichushi Web.
The first case was of a 46-year-old man with a subarachnoid hemorrhage on the basal cistern and bilateral arachnoid cysts in the middle fossa, the second was that of a 29-year-old woman with a subarachnoid hemorrhage at the basal cistern and an arachnoid cyst in the left middle fossa, and the third was that of a 60-year-old man with a right putaminal hemorrhage and contralateral unruptured aneurysm and arachnoid cyst. A literature search for similar cases found 27 patients.
It was difficult to diagnose a ruptured aneurysm in some cases with an arachnoid cyst because computed tomography scan showed atypical findings, such as no hemorrhage, intracystic localized hemorrhage, or subdural hematoma. This review revealed that aneurysms and arachnoid cysts were significantly located ipsilaterally and that they occurred together in relatively young patients.
蛛网膜囊肿和颅内动脉瘤并不罕见，但动脉瘤与蛛网膜囊肿相关却不常见。本研究旨在揭示蛛网膜囊肿与颅内动脉瘤之间的关联。
报告了 3 例同时存在这两种病变的病例，并通过使用 PubMed、Scopus 和 Ichushi Web 对英文和日文文献进行了系统回顾。
第一个病例是一名 46 岁男性，基底池蛛网膜下腔出血和中颅窝双侧蛛网膜囊肿；第二个病例是一名 29 岁女性，基底池蛛网膜下腔出血和左中颅窝蛛网膜囊肿；第三个病例是一名 60 岁男性，右侧豆状核出血，对侧未破裂的动脉瘤和蛛网膜囊肿。对类似病例的文献检索发现了 27 例患者。
由于计算机断层扫描显示不典型的发现，如无出血、囊内局限性出血或硬膜下血肿，一些蛛网膜囊肿患者的破裂动脉瘤难以诊断。本综述显示，动脉瘤和蛛网膜囊肿明显位于同侧，且在相对年轻的患者中同时发生。
