PRIMARY RETROPERITONEAL MUCINOUS CYST: A RARE CASE REPORT IN A FEMALE PATIENT

Abstract

This case report presents the clinical course of a 40-year-old female who presented with abdominal fullness of insidious onset accompanied by a history of hypertension and prior laparoscopic ovarian cystectomy. Imaging studies, including ultrasound and contrast-enhanced CT, revealed a well-defined cystic lesion in the mesentery of the right iliac fossa abutting the ascending colon. Diagnostic laparoscopy revealed a retroperitoneal cyst located posterior to the appendix. The cyst was successfully excised intact using laparoscopic techniques, leading to uneventful postoperative recovery. Histopathological examination confirmed a fibrocollagenous cyst wall lined by a mucin-secreting epithelium.
