Most abdominal hernias can be diagnosed on the basis of findings on physical examination or plain films and barium studies. However, diagnostic dilemmas can arise when patients are obese or have had surgery. Cross-sectional CT scans can show hernias and the contents of the peritoneal sac. More important, CT findings can be used to diagnose unsuspected hernias and to distinguish hernias from masses of the abdominal wall, such as tumors, hematomas, abscesses, undescended testes, and aneurysms. This essay illustrates the CT findings in diaphragmatic hernias, internal hernias, and abdominal wall hernias.
大多数腹外疝可根据体格检查结果、平片及钡剂造影检查作出诊断。然而，当患者肥胖或曾接受手术时，可能会出现诊断难题。横断面CT扫描可显示疝及腹膜囊内容物。更重要的是，CT检查结果可用于诊断隐匿性疝，并将疝与腹壁肿物（如肿瘤、血肿、脓肿、隐睾及动脉瘤）相鉴别。本文阐述了膈疝、内疝及腹壁疝的CT表现。
