Free-floating organized fat necrosis: rare presentation of pelvic mass managed with laparoscopic techniques

Abstract

Free-floating intraperitoneal pelvic masses are exceedingly rare. These abnormalities, typically composed of organized fat necrosis, are most commonly thought to occur after spontaneous torsion and subsequent infarction of an appendix epiploica. Most of these loose bodies are incidentally discovered. Surgical removal is recommended because cross-sectional imaging typically cannot accurately make the diagnosis. Laparoscopy offers a minimally invasive tool to simultaneously inspect the abdominal cavity, assess the pelvic mass diagnosis, and treat the patient. We describe the case of a patient followed up for pudendal neuropathy in which organized fat necrosis was diagnosed and treated by laparoscopy.
