A 4-year-old girl presented repeatedly with a complicated occipital mass, which was erroneously treated as a pyogenic granuloma. Imaging performed before a planned surgical resection detected an underlying intraoccipital dermoid with a sinus tract to the skin surface and extension into the posterior fossa. This case highlights the value of high-resolution computed tomography imaging for depiction of anatomic details and the value of magnetic resonance imaging for differential diagnosis and surgical management. A comprehensive literature review of intraosseous dermoid cyst and detailed discussion of the differential diagnoses are provided.
一名4岁女童反复出现复杂的枕部肿块，曾被误诊为化脓性肉芽肿。在计划进行手术切除前进行的影像学检查发现枕骨内有一个皮样囊肿，伴有通向皮肤表面的窦道并延伸至后颅窝。该病例突出了高分辨率计算机断层扫描成像在显示解剖细节方面的价值，以及磁共振成像在鉴别诊断和手术管理方面的价值。本文提供了骨内皮样囊肿的全面文献综述以及鉴别诊断的详细讨论。
