腹股沟管脂肪瘤CT表现

CT characteristics of inguinal canal lipomas

目的分析腹股沟管脂肪瘤(ICLS)的CT表现。方法回顾性分析104例ICLS患者的CT影像资料,通过MPR图像观察其影像特征。结果 ICLS主要CT表现为腹股沟管内的脂肪密度影,不与腹腔内脂肪相通。104例ICLS患者中,男性(90/104,86.54%)多于女性(14/104,13.46%),差异有统计学意义(χ~2=55.538,P<0.001)。除8例为双侧ICLS外,ICLS左侧病灶(66例)多于右侧(30例),差异有统计学意义(χ~2=13.500,P<0.001)。ICLS最大横截面积为(3.89±2.12)cm^2,男、女性别间ICLS最大横截面积差异无统计学意义(t=1.038,P=0.302)。结论 ICLS患者男性多于女性,病灶多位于左侧,其CT表现具有一定特征,MPR图像有助于ICLS的诊断。

Objective To analyze CT manifestations of inguinal canal lipomas （ICLS）. Methods CT datas of 104 patients with ICLS was retrospectively analyzed. And the imaging features were observed by MPR. Results The main CT manifestations of the ICLS were fat density in the inguinal canal and were unconnected with the abdominal fat. Among the 104 ICLS patients, male （90/104, 86.54%） was more than famale （14/104, 13.46%; χ2=55.538, P〈0.001）. The lesions were located at bilateral sides in 8 cases, left side in 66 cases and right side in 30 cases. The lesions in left side were more than those in right side （χ2=13.500, P〈0.001）. The mean maximum cross-sectional area of ICLS was （3.89±2.12）cm2. There was no statistically significant difference between male and famale in maximum cross-sectional area （t=1.038, P=0.302）. Conclusion In ICLS patients, male is more than famale. And more lesions are located at the left side. The CT manifestations of ICLS have certain characteristics, and MPR images are helpful in diagnosing ICLS.
