A rare peritoneal egg: Case report with literature review

The occurrence of peritoneal loose bodies has been known for hundreds of years. Although rarely, they attain a diameter of more than 5 cm and are then named "giant" peritoneal bodies (gPLBs). Even these huge peritoneal bodies are generally symptom free, but may be linked with chronic symptoms like abdominal pain or discomfort. Many a times, these gPLBs are misinterpreted as intraabdominal tumors or foreign bodies and unnecessary surgical interventions are carried out. We report a rare case of a 75-year-old male, who presented to our tertiary care center emergency department with history of chronic intermittent abdominal discomfort with acute diarrhea and peri-anal pain. Contrast enhanced computed tomography of the abdomen and pelvis revealed round to oval mass in the pelvis measuring 6.2 cm × 5.8 cm. On laparoscopy, a hard, free floating object with the appearance of a boiled egg could just be scooped out from the pelvis. The postoperative pathological examination revealed laminated strands of hyalinized fibro collagenous tissue with central fat necrosis confirming the diagnosis of gPLB. Postoperative period was uneventful. Peritoneal bodies are rare intraabdominal bodies which are either detected incidentally or present with vague symptoms and require interdisciplinary management.
