Presentation
Abdominopelvic pain and palpable mass on physical exam.
Patient Data
A 168×116×154 mm well defined solid mass with a slightly lobulated margin is present at the right adnexa that extends superiorly until the level of the renal hilum. After contrast media injection, the mass shows mild delayed inhomogeneous enhancement. The mass is in closed contact with the uterus fundus, and the right ovary couldn’t be defined separately.
A 25×15 mm well defined subcutaneous mass is noted at posterolateral aspect of chest wall most consistent with sebaceous cyst.
A 42 mm cortical cyst is present at mid portion left kidney.
Case Discussion
The patient underwent right adnexal mass resection, and histopathology evaluation confirmed ovarian fibrothecoma, the most common benign solid ovarian tumor.
The ovarian fibrothecomas usually appear as solid masses with a delayed contrast enhancement. Calcification may be present, and myxoid or cystic degeneration may occur in large masses.
