Penile ossification: A model radiological presentation

A 57-year-old man presented with a 9-month history of painful left curvature of the penis on erection; he also perceived a thick mass in his penis. There was no history of previous trauma, inflammatory penile involvement or metabolic disorder. A physical examination revealed a solid subcutaneous plaque 6 cm long.

An X-ray of the penis revealed a large U-shaped ossification completely involving the proximal and the medial part of the septum both on the dorsal and ventral side (Fig. 1).

The ossifi- cation was fractured using Wilson’s technique [1] and only one case was the disease described as congenital, the penile deformity then corrected by Nesbit’s operation. although it was associated with other anomalies such The ossification was confirmed by microscopy
