Right temporal intradiploic epidermoid cyst: a case report and review of the literature

右側顳骨內表皮囊腫:案例討論及文獻探討

摘要


Intradiploic epidermoid cysts are uncommon, slow-growing, benign tumors, accounting for approximately 1% of intracranial tumors. They can be congenital or acquired; most of them are located intradurally and rarely in the scalp. These lesions usually manifest as painless, gradually enlarging masses over years or decades. They are clinically and radiographically difficult to differentiate from other calvarial lesions. Accurate radiological assessment and complete surgical excision of the lesion and its capsule play a crucial role in ensuring favorable long-term outcomes. We present a case of a young female diagnosed with an epidermoid cyst in the right temporal bone who underwent complete and successful surgical treatment. A complete imaging study was obtained including X-rays and computed tomography and magnetic resonance imaging scans, which demonstrated pathognomonic findings of an epidermoid cyst. We review the relevant literature, pathogenesis, radiographic characteristics, and diagnosis of the epidermoid cysts.

顱骨內表皮囊腫是一種少見、生長緩慢的良性腫瘤,可能是先天性或是後天造成的,多數表皮囊腫位於硬腦膜內,少數長在顱骨之中。這些病灶通常以無疼痛、數年至數十年間緩慢增大的腫塊來表現。我們報告一個年輕女性患有右側顳骨內表皮囊腫接受完整手術療程的病例,並且整理相關文獻探討。
