| 摘 要： | 目的:探讨睑板腺癌（SC）与基底细胞癌（BCC）的CT及MRI表现，提高对二者的鉴别诊断能力。方法:回顾性分析经手术证实的14例SC和7例BCC患者的临床资料和影像表现。结果:在14例SC患者中6例行CT平扫检查，7例行MRI平扫检查，1例行CT与MRI检查；在7例BCC患者中1例行CT平扫检查，5例行MRI平扫检查，1例行CT与MRI检查。SC病例中92.9％ 为女性（13/14），50％ 发生于上睑（7/14），病灶形态多数呈环条状和结节状（12/14），半数病灶边界不清晰（7/14），病灶内常出现“弧形征”（5/14）和气体征（4/7），1例侵犯邻近眼眶组织；BCC病例男女患者比例相近，病灶全部位于下睑（7/7），近半数病灶形态呈结节状（3/7），边界多数较清晰（6/7），1例病灶内见钙化灶，未见病灶侵犯邻近组织。结论:SC与BCC在流行病学、发病部位、影像学特征等方面均有一定的差异，掌握二者鉴别要点可提高术前定性诊断准确性。

| Abstract: | Objective: To improve the ability of differential diagnosis of sebaceous carcinoma of eyelid and basal cell carcinoma by investigating their CT and MRI findings. Methods: The clinical data and imaging findings of 14 patients with sebaceous carcinoma of eyelid and 7 patients with basal cell carcinoma confirmed by operation were retrospectively analyzed and compared. Results: Among the 14 patients with SC, 6 cases underwent CT examination, 7 cases underwent the MRI examination, and 1 case underwent both CT and MRI. Among the 7 patients with BCC, 1 case underwent CT examination, and 5 cases underwent the MRI plain scan, and 1 case underwent both CT and MRI. 92.9% of SC cases were female (13/14). 50% of SC were located in the upper eyelid, and most of them were in the shape of ring strip and nodule (12/14). Half of the lesions had unclear boundaries (7/14). The arc sign (5/14) and gas sign (4/7) often appeared in the lesions. One case invaded the adjacent orbital tissue. The proportion of male and female patients in BCC cases was similar. The lesions of BCC were all located in the lower eyelid (7/7). Nearly half of the shape of the lesions was nodular (3/7). Most of them had clear boundaries (6/7). Calcification was found in one case, and no invasion of adjacent tissue was found. Conclusion: There are some differences in epidemiology, location and imaging features between sebaceous carcinoma of eyelid and basal cell carcinoma. Mastering the key points of differentiation between sebaceous carcinoma of eyelid and basal cell carcinoma can improve the accuracy of preoperative qualitative diagnosis. |
