ABSTRACT

Introduction: “Chocolate cyst” is a common presentation of endometriosis and mainly arises from the ovaries (endometriomas).

Case Report: We present a case of a 43-year-old single nulliparous woman with a five year history of a progressively increasing, painless abdominal mass. Radiological investigations did not give a definite organ of origin but the ultrasound scan suggested it was extra-ovarian. The finding at exploratory laparotomy was that of a huge, 25 kg “chocolate cyst” (confirmed on histology) which was not of ovarian origin and was attached by a peduncle to the uterine fundus.

Conclusion: This case report showed that extra-ovarian chocolate cysts can grow to huge sizes presenting diagnostic dilemma and can also be found on the uterine serosa, amongst other sites.

Keywords: Abdominal mass, Chocolate cyst, Computed tomography, Endometrioma, Extra-ovarian
