“…Penile MRI can be enhanced with intracavernosal injection to produce superior imaging of the tunica albuginea and corpora cavernosa, and demonstrate deformities specific to erections. 10 There are reports of this technique also aiding in the staging of penile cancers. 11,12 In this case, trimix injection was used before the ultrasound and MRI to achieve higher quality anatomical images, and to reproduce the symptomatic state so that potential tumescence-dependent deformities could be demonstrated.…”

Painful erections secondary to rare epithelioid hemangioma of the penis

Epithelioid hemangioma is a rare benign vascular tumour that atypically involves the penis and usually presents as a painful nodule. A 35-year-old man presented with a 5-month history of painful erections without a clinically apparent lesion or deformity. Magnetic resonance imaging (MRI) with pharmacologically induced erection demonstrated a 1.3-cm nodular lesion deep to the skin at the base of his penis. Following local excision of the lesion, which was diagnosed as an epithelioid hemangioma, the patient was symptom free. This case demonstrates a rare etiology of painful erections with a unique presentation. To the authors' knowledge, it is also the first report of MRI with intracavernosal injection of trimix to assess for a specific cause of painful erections.

Peyronie's disease also known as penile fibromatosis and plastic induration of the penis is a cause of painful erection. It is rare with a prevalence rate of 0.4-9 %. It may be associated with Dupuytren's contracture. Though its etiopathogenesis is uncertain, presence of fibrin plaque and usual dorsal location is suggestive of aberrant healing response to minor penile trauma from shear stress. Ultrasound is useful in quantifying the fibrotic involvement in Peyronie's disease, determining the precise location of the lesion in the penis (dorsal / ventral / circumferential / septal), length, width and thickness of the plaque. It can detect fibrotic changes which have not yet calcified. We report two different cases of Peyronie's disease with calcification in intercorporeal septum alone and another case with calcified plaque in intercorporeal septum extending along the ventral aspect of both corpora cavernosa.

“…6 Also magnetic resonance (MR) imaging is potentially useful to assess the penile rupture; the key finding is disruption of the low-signal intensity tunica albuginea, which is well-seen on both T1 and T2 weighted images, although T1 weighted sequences may detect more subtle fractures. 7 Treatment may be either conservative or immediate surgery. The conservative management of penile fracture includes splinting, cold compresses and a combination of anti-inflammatory, analgesic medication and fibrinolytics.…”

E347 research researchCite as: Can Urol Assoc J 2013;7(5-6):e347-50. http://dx.doi.org/10.5489/cuaj.1209 Published online May 13, 2013. AbstractA 22-year-old man reported cracking sound and acute pain during sexual intercourse followed by rapid penile detumescence and ecchymosis. He experienced more pain because he could not urinate and had a palpably full bladder. Moreover, his urethra was bleeding. Physical examination revealed swollen, ecchymotic and deviated penis and penis ultrasonography showed an injury of the tunica albuginea and Buck's fascia with an expanding hematoma. Suprapubic catheter was positioned. Surgical exploration revealed a tear of tunica albuginea of both corpora cavernosa and complete urethral dissection. End-to-end urethral anastomosis and suture of corpora cavernosa lesion were performed. Vescical catheter was mantained for 6 days and suprapubic catheter for 3 months to allow a complete urethral healing. A pseudodiverticulum was found at anastomosis level on the urethrocistography 1 month after surgery. It disappeared by allowing micturition via the suprapubic catheter. The patient presented regular urinary flow and physiological erections 30 days later. In our experience, prompt surgical repair preserved erectile function and keeping the suprapubic catheter protected the urethra; this was the correct management for repairing the urethral lesion.
