Presentation

Severe lower abdominal pain for 1 day

Patient Data

Age: 25 years

Axial post-contrast images of the abdomen show a large non-enhancing cystic lesion measuring 9 x 8 x 8 cm superior to the urinary bladder. The minimally enhancing heterogeneous solid lesion adjacent to the cyst represents a twisted right ovary.

Coronal post-contrast images depict the relationship of the cyst with the twisted right ovary and the urinary bladder. There is trace free fluid in the pelvic cavity.

The left ovary is normal in position and attenuation. 

Case Discussion

The patient underwent emergency laparotomy and right oophorectomy was performed for the twisted ovarian cyst. Biopsy revealed the lesion to be a serous cystadenoma of the ovary.
