ABSTRACT
Inguinal swelling is a common clinical finding and the most common cause is inguinal hernia. Outside the hernias; inguinal swelling may occur due to common causes such as lymph nodes, hematoma and abscess. In addition, inguinal swelling can be seen due to rare causes such as spermatic cord tumors, endometriosis, leiomyoma, round ligament varices and retroperitoneal masses. Herein, we present the findings of contrast-enhanced abdomen computed tomography examination of collateral vascular structures between the paraumbilical vein and the left femoral vein due to portal hypertension in a 39-year-old male patient who complained inguinal swelling.
