Ossifying renal tumor of infancy presenting as a palpable abdominal mass.
We report a case of ossifying renal tumor of infancy, which presented as a palpable abdominal mass in an otherwise asymptomatic 10-month-old girl. The tumor was partially calcified and occupied the renal pelvis, causing severe hydronephrosis. The differential diagnosis for a patient this age included Wilms tumor, extra-adrenal neuroblastoma, infection, calculus, calcified hematoma and ossifying renal tumor of infancy. The child underwent heminephrectomy and is currently doing well.
