BANNURA C, GUILLERMO; CONTRERAS P, JAIME  e  PENALOZA M, PAULINA. Giant pelvic and abdominal omental cyst. Report of one case. Rev Chil Cir [online]. 2008, vol.60, n.1, pp.67-70. ISSN 0718-4026.

We report a 41 years old women presenting with abdominal and pelvic pain lasting six weeks. She had a history of hysterectomy three years ago. Abdominal ultrasound and CAT scan showed a giant cystic lesion of 15 x 8 x 12 cm that occupied a great portion of the abdomen and pelvis. After a partial resection and marsupialization, she was refereed to surgery due to an early relapse of the cyst. She was operated again, performing a complete cyst excision and bilateral anexectomy, with a good postoperative evolution. Pathology confirmed the diagnosis of a simple omental cyst. The unilocular feature of the lesion is characteristic of omental cysts. However, due to the pelvic location and dimensions, the differential diagnosis must be made with benign cystic mesothelioma, that had a high rate of relapse and may become malignant
