Meningiomas associated with intracranial aneurysms are very rare. The co-existence of both lesions is not only a diagnostic challenge but also has important therapeutic implications. We analyzed our experience of five such patients, the second largest group in the literature. All the lesions were successfully managed surgically. All the patients were female. The location of the meningioma was clinoidal (2), planum sphenoidale (1), petroclival (1) and pterional (1). Three patients had posterior communicating (PCOM) artery aneurysm associated with meningioma. The other aneurysms were internal carotid artery (ICA) and anterior communicating artery (ACOM). One patient with pterional meningioma had an anomalous meningeal artery arising from the right ophthalmic artery. In three patients both lesions underwent treatment at the same sitting. In two patients meningioma underwent excision first followed by aneurysm clipping. From our experience the incidence of meningiomas associated with aneurysms was 1.1%, which is not higher than the incidence of aneurysms in the general population.
与颅内动脉瘤相关的脑膜瘤非常罕见。这两种病变的并存不仅是一个诊断挑战，而且具有重要的治疗意义。我们分析了 5 例此类患者的经验，这是文献中第二大的一组患者。所有病变均成功手术治疗。所有患者均为女性。脑膜瘤的位置为岩骨尖（2 例）、蝶骨平台（1 例）、岩斜区（1 例）和翼点（1 例）。3 例患者与后交通动脉动脉瘤（PCOM）相关，另 2 例为颈内动脉（ICA）和前交通动脉动脉瘤（ACOM）。1 例翼点脑膜瘤患者有一根异常脑膜动脉发自右侧眼动脉。在 3 例患者中，两种病变在同一时间接受了治疗。在 2 例患者中，脑膜瘤首先切除，然后夹闭动脉瘤。根据我们的经验，与动脉瘤相关的脑膜瘤的发生率为 1.1%，并不高于一般人群中动脉瘤的发生率。
