Corpus spongiosum Einriss

Penile trauma

- Corpus spongiosum tear. Yellow arrows: Non-enhanced CT showing a voluminous and slightly hypodense corpus spongiosum.

Penile trauma

- Corpus spongiosum tear. Contrast extravasation in the penile bulb (yellow arrow) and anterior extension within the corpus spongiosum (red arrows). Extravasated contrast show an increased size as well as a different morphology, suggesting active bleeding.

Penile trauma

- Corpus spongiosum tear. Green arrow: Suprapubic catheter used to perform an antegrade cystourethrogram. Blue arrow: Foley catheter tip in the anterior urethra (penile segment) with an inflated balloon at the end, to prevent contrast reflux.

Penile trauma

- Corpus spongiosum tear. Note the stricture in membranous urethra, probably caused by the previous traumatic injury or the ischemic injury of embolisation (yellow arrows).

Penile trauma

- Corpus spongiosum tear. Red arrow: Introducer; Green arrow: Diagnostic catheter; Yellow arrow: Left internal pudendal artery contrast blush.

Penile trauma

- Corpus spongiosum tear. Coronal view: - Yellow arrows: Penile bulb / - Red arrows: anterior extension of contrast within corpus spongiosum / - Orange arrow: Urethral extension of contrast. Normal penile anatomy: Corpus cavernosus (green arrows), corpus spongisoum (black arrow).

Penile trauma

- Corpus spongiosum tear. Note the contrast extravasation from the left internal pudendal artery (red arrow). After using absorbable haemostatic gelatin sponge, active bleeding was interrupted (blue arrow).

Penile trauma

- Corpus spongiosum tear. At the same time, contrast extravasation from the right internal pudendal artery was observed (red arrow) and the use of absorbable gelatin sponge was required (green arrow). Active bleeding was interrupted (blue arrow).

Penile trauma

- Corpus spongiosum tear. After a few minutes, a new focus of contrast extravasation originating in the right internal pudendal artery was observed (red arrow). A selective angiography was performed using a micro-catheter (green arrow), confirming the bleeding.

Penile trauma

- Corpus spongiosum tear. A liquid embolic agent (red arrow, Onyx) was injected through a micro-catheter. Blue arrow: gauze pad.

Penile trauma

- Corpus spongiosum tear. At the same time, another focus of contrast extravasation originating in the left pudendal artery was also observed (red arrow) and required the use of a liquid embolic agent (blue arrow, Onyx).

Penile trauma

- Corpus spongiosum tear. After the procedure, a pelvic plain film was performed. Note the presence of bilateral liquid embolic agent (Onyx) in both internal pudendal arteries.
