目的分析眶区皮样囊肿及表皮样囊肿的CT表现,揭示该病的特殊性CT征,作为诊断依据.方法复习经手术及病理组织学证实的皮样及表皮样囊肿CT片共55例,分析其所在位置、范围、形状、边界、密度、CT值及继发改变.结果 55例病变均被CT发现,53例提示病理组织学诊断,2例眶缘有瘘管者缺乏特征性CT表现.病变位于眶内者44例:内上象限2例、外上象限36例、内下象限3例、外下象限3例;按所在间隙分析,中央间隙(肌锥内)1例、周围间隙9例、骨膜下间隙24例、眶骨壁内10例.眶缘者5例均位于眶上缘.颞窝者6例均位于颞肌下.囊肿密度不均,CT值-158.67Hu～+62.00Hu.典型的骨壁改变45例.结论 CT能够在术前对皮样囊肿作准确定性、定位诊断,对制定手术方案有很大帮助.

Objective To study the findings of the orbit dermoid and epidermoid cyst on CT, then to reveal the CT characteristics of the disease for diagnosis. Methods To reviewing the CT image of 55 cases, all had proved by histopathology or operation. And to analyze its position, extent, shape, boundary, density, CT value and subsequent changes. Results CT could discover all the lesions. Fifty-three CT findings indicated its histopathology diagnosis and 2 patients with orbit margin fistula lacked CT characteristics. There were 44 cases in the orbit, 2 in the upper inner quadrant, 36 in the upper outer quadrant, 3 in the lower inner quadrant, 3 in the lower outer quadrant, 1 in the muscle cone, 9 in the space between muscle cone and periosteum, 24 in the subperiosteal space, 10 in the bone wall. There were 5 cases in the margo supraorbitalis, 6 under the temporalis.The density of the cysts was heterogeneity, and the CT value was from -158.67Hu to +62.00 Hu. Forty-five cases with typical boll wall changes were found. Conclusions Orbital CT scanning is the effective way in the preoperative diagnosis of orbital dermoid and epidermoid cysts for determining its nature and location. It is helpful to formulating the procedures of operation.
