The standard investigation for confirmation of diagnosis is CECT of the abdomen. The presence of a spongiform mass in the peritoneal cavity on CECT imaging is characteristic of gossypiboma.[4] Once diagnosed, removal of the foreign body is necessary to prevent future unwanted complications. Intense inflammatory reaction induced by gossypiboma leads to the formation of extensive intra-abdominal granulations and adhesions. Hence, open exploration is preferred over minimally invasive techniques for retrieval of gossypiboma.
