Introduction: Large abdominopelvic cystic masses in post-hysterectomy patients present significant diagnostic challenges due to altered pelvic anatomy and overlapping radiological features. Peritoneal inclusion cysts may closely mimic ovarian neoplasms on imaging, leading to diagnostic uncertainty.
Presentation of Case: A 55-year-old woman, eight years post vaginal hysterectomy, presented with progressive abdominal distension and abdominal discomfort. Clinical examination revealed a large cystic mass occupying the lower and central abdomen. Routine laboratory investigations and tumor markers, including CA-125 and CEA, were within normal limits. Magnetic resonance imaging suggested a peritoneal inclusion cyst, and both ovaries could not be clearly visualized. Diagnostic laparoscopy failed to identify the origin of the lesion, necessitating conversion to exploratory laparotomy. A giant cystic mass arising from the left ovary was excised in toto, along with right salpingo-oophorectomy. Histopathological examination confirmed benign mucinous cystadenoma of the left ovary.
Discussion: Giant ovarian mucinous cystadenomas may lose their typical adnexal appearance and present as diffuse abdominopelvic cystic masses, particularly in patients with prior pelvic surgery. Limitations of imaging modalities and distorted pelvic anatomy contribute to frequent misdiagnosis. This case emphasizes the importance of maintaining clinical suspicion and considering surgical exploration when radiological findings are inconclusive.
Conclusion: Ovarian mucinous cystadenomas should be considered in the differential diagnosis of large abdominopelvic cystic masses in post-hysterectomy patients. Timely surgical intervention remains essential for definitive diagnosis and effective management.
