目的 探讨眼球表面结膜皮样瘤及皮脂肪瘤的临床、病理及CT特征,评价CT检查的价值。方法 回顾性分析手术病理证实的眼球表面结膜皮样瘤及皮脂肪瘤12例,其中皮样瘤5例,皮脂肪瘤7例。女性多于男性(11∶1),均为单眼单个病灶,右眼多于左眼(9∶3)。术前均行常规眼眶CT横断面扫描,其中5例行增强扫描,分析其临床、病理及CT特征。结果 CT上病灶均表现为附着于眼环颞侧的新月形低密度影,最大25mm×15mm,最小8mm×5mm,外缘结膜下均有1~3mm厚的囊壁,增强后囊壁中度强化。皮样瘤较小,壁较厚,CT值-55~-75HU。皮脂肪瘤较大,壁较薄,CT值-80~-120HU。结论 CT检查可明确病灶的大小、范围、性质,以及与眼环、外直肌、泪腺等的关系,有助于提高手术成功率,减少并发症。
Objective To investigate the clinical features, pathology and CT features of conjunctival dermatophytes and sebaceous tumors on the surface of the eye and to evaluate the value of CT examination. Methods Retrospective analysis of surgical pathology confirmed 12 cases of ocular surface conjunctival dermatoid tumors and sebaceous tumors, including 5 cases of dermatosis and 7 cases of sebaceous lipoma. More women than men (11: 1), were monocular lesions, right eye than the left eye (9: 3). Preoperative routine orbital CT scan, 5 cases of enhanced scanning, analysis of its clinical, pathological and CT features. Results All the CT lesions showed crescent-shaped low-density shadow attached to the temporal eye. The maximal diameter was 25mm × 15mm, the smallest was 8mm × 5mm, and the outer wall was 1-3mm thick. Degree enhancement. Small dermatosis, wall thicker, CT value -55 ~ -75HU. Seborrheic tumor larger, thinner wall, CT value -80 ~ -120HU. Conclusion The CT examination can confirm the size, scope, nature of the lesion, and the relationship with the eye ring, lateral rectus, lacrimal gland and so on, which helps to improve the success rate of operation and reduce the complications.
