Abstract
Parasitic leiomyoma (PL) is an exceedingly rare type of leiomyoma characterized by the distribution of multiple nodules across various organ surfaces within the pelvic and abdominal cavities, mimicking malignant tumor implants. PLs originating from the greater omentum are notably rare, with few cases reported thus far. Their nonspecific clinical presentations, such as abdominal distension, ascites, and urinary difficulties, often lead to their misidentification as abdominal malignancies. The considerable mobility of the greater omentum facilitates PL torsion, potentially causing ischemic necrosis of the tumor mass and presenting as acute abdomen, which complicates diagnosis further. Clinicians should consider the possibility of PLs of the greater omentum in patients with a history of uterine fibroids or prior fibroid surgeries. This review highlights a case of a patient who experienced sudden onset abdominal pain eight years after undergoing laparoscopic myomectomy. Intraoperative findings confirmed torsion and necrosis of a PL on the greater omentum, leading to the surgical removal being deemed the most suitable treatment method.
