This article describes the case of a dermoid cyst with unique radiological findings in an unusual location. This cyst arose from the anterior clinoid process and projected into the right frontal lobe in a 39-year-old man. CT and MRI revealed a gravity dependent level within this low density lesion. Stereotaxic biopsy revealed that this gravity dependent level was formed between layers of fat and fluid. Craniotomy later showed the presence of hair within this lesion. The literature concerning the radiographic findings and location of dermoid brain cysts is also reviewed.
本文描述了一例皮样囊肿病例，其在不寻常的位置具有独特的放射学表现。该囊肿起源于前床突，并向一名39岁男性的右侧额叶突出。CT和MRI显示在这个低密度病变内有一个重力依赖平面。立体定向活检显示这个重力依赖平面是在脂肪层和液层之间形成的。后来的开颅手术显示该病变内存在毛发。本文还回顾了有关脑皮样囊肿的影像学表现和位置的文献。
