Serous cystadenoma with omental caking and ovarian torsion: an unusual case presentation.
BACKGROUND
This case evaluates a patient with abdominal pain who presented with a pelvic mass and imaging studies suspicious for malignancy.


METHODS
A 21-year-old, gravida 0, para 0, was admitted after presenting to the outpatient with abdominal pain. Ultrasound revealed a large 17 x 20 cm pelvic mass with solid and cystic components. CT scan revealed worrisome findings including the finding of "omental caking" and nodal enlargement. CA 125 was elevated at 85 U/ml. Final pathology after surgical removal of the mass showed evidence of serous cystadenoma with ovarian torsion without signs of malignancy. The patient had an unremarkable postoperative course and was discharged in stable condition.


CONCLUSIONS
Although uncommon, pelvic masses that are benign may mimic malignant masses with extradnexal inflammation.
