Peritoneal loose bodies, or peritoneal mice, are rare asymptomatic lesions that are usually found as an incidental finding during abdominal surgery or autopsy. Giant peritoneal loose bodies are rare. Giant loose bodies, measuring more than 5 cm, are rare and only a few cases are reported in the literature. These bodies are usually infarcted appendices epiploicae, which become detached and appear as a peritoneal loose body in the abdominal cavity. We present a rare case large peritoneal loose body "peritoneal mice" found during a laparoscopic abdominal surgery in a 70 years old male patient. Usually these peritoneal loose bodies are left untreated until complication arises.
