Inguinal canal lipomas are a frequent, often unrecognised finding on abdominopelvic CT. Commonly referred to as spermatic cord or round ligament lipomas, they are not true tumours of fat but are extrusions of extraperitoneal fat into the inguinal canal. Their fat content and shared location in the inguinal canal result in confusion with fat-containing inguinal hernias with which they often coexist. As laparoscopic herniorrhaphies proliferate, greater awareness of the condition by radiologists is needed to provide accurate preoperative information. This pictorial essay highlights the differentiating diagnostic features of inguinal canal lipomas and fat-containing inguinal hernias.
腹股沟管脂肪瘤在腹盆腔CT检查中很常见，但常常未被识别。它们通常被称为精索或圆韧带脂肪瘤，并非真正的脂肪肿瘤，而是腹膜外脂肪向腹股沟管的突出。其脂肪成分以及在腹股沟管中的共同位置，导致它们常与含有脂肪的腹股沟疝相混淆，且二者常并存。随着腹腔镜疝修补术的普及，放射科医生需要提高对这种情况的认识，以便提供准确的术前信息。这篇图文文章重点介绍了腹股沟管脂肪瘤和含有脂肪的腹股沟疝的鉴别诊断特征。
