Bilateral Pelvic Kidney Masquerading as Horseshoe Kidney in Fanconi Anemia.

Fanconi anemia (FA) is a genetic disease associated with a risk of congenital malformations, bone marrow failure, and a predisposition to cancer. Congenital abnormalities of the kidney and urinary tract are not infrequent in FA, with renal ectopia being among them. The incidence of bilateral pelvic kidney is restricted to only a few reported cases; however, its association with FA has never, to our knowledge, been reported in the literature. We present a case of FA in a girl whose 99mTc-dimercaptosuccinic acid planar scan showed apparently fused kidneys, which were confirmed to be bilateral pelvic kidney on hybrid cross-sectional imaging.
