Abstract
BACKGROUND: Diphallia poses several surgical, psychological, and esthetic issues. Currently, diphallia is only diagnosed after birth. CASE: We present a true diphallia in one fetus of dichorionic twins noted at 23 weeks of gestation. In this fetus, two phallus-like protrusions and a bifid scrotum, as well as a duplicated collecting system of both kidneys, were found on ultrasonogram. Unfortunately, the fetus died near term. CONCLUSION: Diphallia, although exceedingly rare, can be precisely diagnosed antenatally. Careful ultrasound examination of the origins of the fetal phallus and of other adjacent organs is essential to establish the diagnosis of diphallia and to detect any associated anomalies.
