[MRI of the post-traumatic penis]. / IRM de la verge: intérêt dans le bilan post-traumatique.

Penile trauma, though rare, requires specialized management. Fibrotic sequelae from lesions of the tunica albuginea and corpora cavernosa must be prevented given their impact of the erectile function. Knowledge of penile anatomy enables acquisition and interpretation of penile MRI, preferably performed in the first few hours following injury. Tear of the tunica albuginea must be identified since it requires surgical management. Other lesions may be present at the acute (hematoma) or chronic (fibrosis, arteriocavernous fistula) phases. MRI, non-invasive and painless, is the imaging modality of choice in the multiplanar evaluation of traumatic injuries of the penis.
