A Large Complex Ovarian Cyst Mimicking a Fibroid

Clinical History

A 54-year old lady presented with a large mass in the centre of the lower abdomen mimicking a fibroid.

Case Description

Ultrasound performed (TA and TV) revealed a large 21 cm complex cystic mass (complex ovarian cyst) emanating from the pelvis into the abdomen with multiple septations within it.

A subsequent MRI pelvis confirmed the large multicystic pelvic lesion to be a possible neoplasm arising from the left ovary.

The patient had a whole body contrast staging CT that revealed no extra-ovarian disease presence.

Diagnosis/ Discussion/ Treatment/ Follow up

Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed and the cyst was analysed histologically. Histology revealed the lesion to be a benign mucinous cystadenoma.
