An unusual mass in unusual gender

A 62-year-old-woman with abdominal pain and right leg claudication was admitted to our catheterization laboratory for diagnostic peripheral arteriography. Physical examination was notable for a palpable mass in the right iliac fossa. Her medical history was unremarkable except for hysterectomy. Diagnostic abdominal and peripheral arteriography revealed egg-shaped mass with sharp borders (Fig. 1, Video 1, 2). Routine laboratory tests were within normal limits. Abdominal contrast-enhanced computed tomography (CT) showed a huge pelvic mass approximately 10x10 cm in diameter with linear calcifications, located posterior to the bladder and extending beyond the pelvis (Fig. 2).
