The authors describe the computer tomography appearances of intracranial epidermoid and dermoid cysts as demonstrated by three cases, and review the published literature. Dermoid and epidermoid cysts can be distinguished from each other by their topography (dermoid cysts are found more medially while epidermoid cysts occur on the base of the skull and in the pontocerebellar angle), by the presence or not of calcification (found almost exclusively in dermoid cysts), and by their computer tomography appearances. Both tumors have low densities, below that of the cerebrospinal fluid, but dermoid cysts have lower densities than epidermoid cysts, which can be easily explained by referring to the anatomo-pathological appearance.
作者描述了3例颅内表皮样囊肿和皮样囊肿的计算机断层扫描表现，并回顾了已发表的文献。皮样囊肿和表皮样囊肿可通过其位置（皮样囊肿多位于内侧，而表皮样囊肿发生于颅底和桥小脑角）、有无钙化（几乎仅见于皮样囊肿）以及计算机断层扫描表现来相互区分。两种肿瘤密度均较低，低于脑脊液，但皮样囊肿的密度低于表皮样囊肿，这可通过参考解剖病理学表现很容易地解释。
