A Rare Case of Peritoneal Loose Body (Mice) in Left Sided Inguinal Hernial Sac

Background: Peritoneal loose bodies or peritoneal mice are calcified pieces of necrotic tissue found in the peritoneal cavity. They are usually asymptomatic and small, ranging from 0.5 to 1 cm in size, but rarely may be up to 5 to 10 cm in size [1]. Peritoneal loose bodies develop from Appendices epiploicae that has undergone axial rotation followed by necrosis of its pedicle and detachment. Peritoneal loose bodies are incidental finding at laparotomy [2] but they are rarely described in hernial sac in the literature. By this article I have attempted to describe the rare case report of this subject to add to the scarce literature on this subject

Case report: One such loose body of 2*2 cm size was found intraoperatively in a 45-year-old male patient presented to civil hospital Ahmedabad with left sided inguinal hernia & operated at Civil Hospital, Ahmedabad in the indirect inguinal hernial sac. Left inguinal hernioplasty was done and excised sac with containing loose body was sent for histopathology which confirmed it to be a peritoneal loose body.
