Bilateral ovarian fibromas with duplex collecting system and ectopic ureter in an 11-year-old girl: a case report with genetic analysis.

ABSTRACT:

Background

Bilateral ovarian fibromas in children are exceedingly rare. Their coexistence with congenital anomalies of the kidney and urinary tract (CAKUT) has not been reported.

Case presentation

An 11-year-old girl presented with abdominal pain and lifelong urinary dribbling. Imaging revealed bilateral ovarian masses and a left duplex collecting system with a dilated upper-pole ureter inserting ectopically into the posterior urethra. Serum tumor markers including CA125 were within normal limits. No ascites or peritoneal deposits were identified. Laparoscopic bilateral tumor excision preserved normal ovarian tissue; histopathology confirmed ovarian fibromas with low proliferative index. Three months later, laparoscopic excision of the ectopic distal ureteral segment and ips
