The double skull sign (DSS) is a unique image on the outside of the brain that looks like two skulls. Whereas congenital and acquired types of DSS have been reported, the etiology of both of them is calcified hematomas. We encountered a case of a 46-year-old woman with a history of subarachnoid hemorrhage followed by cranioplasty at 43 years old. She developed right hemiparalysis and motor aphasia suddenly. Brain computed tomography and magnetic resonance imaging revealed not only cerebral infarction but also DSS incidentally. After detailed analysis, we concluded that the DSS in this case was not due to calcification of the hematoma but was related to the cranioplasty. In this report, we present an interesting case and discuss etiologies of the development of DSS after cranioplasty.
双颅骨征（DSS）是一种出现在脑外的独特影像，形似两个颅骨。尽管已有先天性和后天性双颅骨征的报道，但二者的病因均为钙化血肿。我们遇到一例46岁女性，有蛛网膜下腔出血病史，43岁时接受了颅骨成形术。她突然出现右侧偏瘫和运动性失语。脑部计算机断层扫描和磁共振成像不仅显示有脑梗死，还意外发现了双颅骨征。经过详细分析，我们得出结论，该病例中的双颅骨征并非由血肿钙化所致，而是与颅骨成形术有关。在本报告中，我们展示了一个有趣的病例，并讨论了颅骨成形术后双颅骨征形成的病因。
