Preperitoneal lipoma: case report

Abstract

Introduction: lipomas are benign tumors that can occur anywhere in the body, although their preperitoneal location is rare and uncommon.
Clinical case: a 65-year-old woman presented with intermittent, stabbing abdominal pain in the right flank and hypochondrium, lasting for 20 days. She had a history of laparoscopic cholecystectomy performed nine months earlier, during which a mass was noted in the right hypochondrium's parietal peritoneum. A plain and contrast-enhanced abdominal CT scan was requested, revealing a hypodense mass with fat attenuation characteristics, located between the right transverse abdominal muscle and the outer edge of the liver, consistent with a lipoma. The mass was removed laparoscopically without complications, and the patient experienced a favorable recovery.

Conclusion: preperitoneal lipomas are rare and uncommon. Laparoscopic surgery allowed for complete resection of the lipoma and rapid recovery of the patient.
