Objectives: Gauze remnants form gauzeomas after surgery, if infection has not occurred. We present a case of gauzeoma diagnosed after surgery.
Patient: A 72-year-old man noticed a mass in his lower abdomen. He had undergone surgery for left inguinal hernia 21 years ago. A retroperitoneal mass was found on computed tomography (CT) and magnetic resonance imaging (MRI), and he was then referred to our hospital. A detailed abdominal ultrasonography, CT, and MRI revealed a cystic mass with a bulkhead-like structure near the bladder. These findings indicated the possibility of a malignant cyst; hence, an open surgery was performed to excise the mass. Macroscopically, the specimen was clearly bound, covered with a capsule, and filled with pus and had a gauze inside.
Results: Based on the patient history and position of the mass, it was diagnosed as gauzeoma, which had strayed into the retroperitoneal cavity during the surgery for inguinal hernia.
Conclusion: The imaging findings of gauzeoma are diverse; hence, it is often difficult to diagnose without surgery. However, gauzeoma can be lethal if the cystic mass is infected; thus, it is important to diagnose it correctly.
