BACKGROUND
Though familial intracranial aneurysms are well documented, only a few cases of intracranial aneurysms in identical twins have been reported.
CASE REPORT
Our patient, a 46-year-old woman, presented with a subarachnoid hemorrhage (SAH) due to a ruptured aneurysm. At the age of 36, her identical twin sister had also suffered SAH from a ruptured aneurysm. Both twins were treated successfully.
CONCLUSION
The likelihood of the occurrence of an aneurysm may be higher for a twin whose identical twin has developed an aneurysm than for the general population. Therefore, it is reasonable to perform certain screening procedures for aneurysms on an asymptomatic twin when the other presents with SAH due to a ruptured aneurysm.
背景
虽然家族性颅内动脉瘤已有充分记载，但同卵双胞胎患颅内动脉瘤的病例仅报道过少数几例。
病例报告
我们的患者是一名46岁女性，因动脉瘤破裂导致蛛网膜下腔出血（SAH）。36岁时，她的同卵双胞胎姐妹也曾因动脉瘤破裂发生SAH。这对双胞胎均成功接受了治疗。
结论
同卵双胞胎中有一人患动脉瘤，另一人发生动脉瘤的可能性可能高于普通人群。因此，当同卵双胞胎中的一人因动脉瘤破裂出现SAH时，对无症状的另一人进行某些动脉瘤筛查程序是合理的。
