Prenatal diagnosis of a rare variant of hypospadias and review of the literature.

We present a case of a variant of hypospadias, diagnosed prenatally at 21 weeks' gestation, in which the penis and scrotum appeared normal but there was a cyst-like lesion and a urethrocutaneous fistula on the ventral side of the penis. Detailed sonographic examination and karyotyping confirmed this was an isolated lesion and helped the parents to decide on continuation of the pregnancy.
