title: Antenatal hydroureteronephrosis presenting as an apparent solid renal mass.
abstract: We present a patient with an apparent renal mass that was identified antenatally with pyelocaliectasis and ureterectasis. A right ectopic ureter with an apparent cystic upper pole was eventually confirmed at 5 months of age. The definitive diagnosis in this case eluded an initial exhaustive neonatal radiologic and surgical evaluation.
