We reported a unique case of posttraumatic giant infratentorial extradural intradiploic epidermoid cyst. A 54-year-old male, with a previous history of an open scalp injury and underlying linear skull fracture in the left occipital region in childhood, presented with a painful subcutaneous swelling, which had been developed gradually in the same region and moderate headache, nausea, vomiting and cerebellar ataxia. The duration of symptoms on admission was 3 months. Imaging studies revealed occipital bone destruction and giant extradural intradiploic lesion. The preoperative diagnosis was giant infratentorial extradural intradiploic epidermoid cyst. Surgery achieved total removal of the lesion, which was histologically confirmed and the postoperative course was uneventful. To our knowledge, this is the first case of giant infratentorial extradural intradiploic epidermoid cyst with a traumatic etiology described in the literature.
我们报告了一例独特的创伤后巨大幕下硬膜外板障内表皮样囊肿病例。一名54岁男性，童年时有左枕部开放性头皮损伤及潜在线性颅骨骨折史，现出现疼痛性皮下肿胀，该肿胀在同一区域逐渐形成，伴有中度头痛、恶心、呕吐及小脑共济失调。入院时症状持续时间为3个月。影像学检查显示枕骨破坏及巨大硬膜外板障内病变。术前诊断为巨大幕下硬膜外板障内表皮样囊肿。手术实现了病变的全切，术后经组织学证实，术后病程平稳。据我们所知，这是文献中描述的首例具有创伤病因的巨大幕下硬膜外板障内表皮样囊肿病例。
