Diphallia or duplication of the penis is an extremely rare but well-documented anomaly. According to the presence of one or two corpora cavernosa in each of the penises, diphallia is classified into two major groups of bifid phallus or true diphallia, respectively. We report a 5-year-old boy with duplication of the penis. Significant separation of the penises and their morphology made them appear as true complete phalluses, but MRI established the definitive diagnosis of bifid phallus by demonstrating the presence of one corpus cavernosum in each penis. MRI is a valuable method for achieving the accurate diagnosis of these anomalies and associated malformations. It also provides the appropriate knowledge regarding anatomical detail and assists the surgeon in decision making and preoperative planning for the optimal surgical approach.
