Two cases of extradural epidermoid cyst and one case of xanthoma are reported in order to describe the computed tomographic and other radiographic findings. Contrast enhancement of the margin was seen in all of the cases. Absorption values almost as low as those found with cerebrospinal fluid were present in the central region of the lesions.
报告了2例硬膜外表皮样囊肿和1例黄瘤病病例，以描述计算机断层扫描及其他影像学检查结果。所有病例均可见边缘强化。病变中央区域的吸收值几乎与脑脊液的吸收值一样低。
