Normal enhancement of the corpus spongiosum

Case Discussion

The corpus spongiosum enhances almost immediately post contrast; however, the corpora cavernosa enhances gradually in a centrifugal fashion. This pattern of enhancement is due to the central location of the cavernosal artery 1​.

The following enhancement of the corpus spongiosum perplexed his treating team.

The patient was not able to urinate at the time. Examination revealed no bruising or trauma to the perineum or the genitalia. It was concluded that this was normal enhancement of the corpus spongiosum. 

That evening the patient was able to urinate with no macroscopic hematuria noted. He was kept under the trauma team for observation.
