“…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. To the authors' knowledge, this is the first reported case of penile MRI with intracavernosal injection to assess for a specific cause of painful erections.…”

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.

“…For assessment of cavernosal viability in priapism, the dynamic scans show early perfusion, but there should be one scan at least 10 min after contrast-ideally a small field of view spin echo T 1 weighted sequence, with an identical sequence obtained before contrast for comparison. Contrast enhancement for staging tumours is usually not helpful [7].…”

ABSTRACT. MRI of the penis is an expensive test that is not always superior to clinical examination or ultrasound. However, it shows many of the important structures, and in particular the combination of tumescence from intracavernosal alprostadil, and highresolution T 2 sequences show the glans, corpora and the tunica albuginea well. In this paper we summarise the radiological anatomy and discuss the indications for MRI. For penile cancer, it may be useful in cases where the local stage is not apparent clinically. In priapism, it is an emerging technique for assessing corporal viability, and in fracture it can in most cases make the diagnosis and locate the injury. In some cases of penile fibrosis and Peyronie's disease, it may aid surgical planning, and in complex pelvic fracture may replace or augment conventional urethrography. It is an excellent investigation for the malfunctioning penile prosthesis.

“…These modalities would be reserved for lesions in which an adequate exam could not be performed, such as in the morbidly obese patient. However, the use of an intracavernosal injection of prostaglandin E1 as an adjunct prior to MRI scan has shown promise in some series by improving its accuracy in assessing the clinical stage of the primary tumor (13,14). The sensitivities and specificities, respectively, for this modality in correctly assessing clinical T1 tumors are 85% and 83%, for T2 tumors 75% and 89%, and for T3 tumors 88% and 98% (14).…”

Purpose: The management of penile cancer has evolved as less invasive techniques are applied in the treatment of the primary tumor and inguinal lymph nodes. Materials and Methods: Herein we review the literature focusing on advances in the preservation of the phallus as well as less morbid procedures to evaluate and treat the groins. Results: Promising imaging modalities for staging are discussed. New techniques are described and tables provided for penile preservation. We also review the contemporary morbidity of modified surgical forms for evaluation of the inguinal nodes. Conclusions: Advances in surgical technique have made phallic preservation possible in a greater number of primary penile cancers. The groins can be evaluated for metastasis with greater accuracy through new radiologic means as well as with less morbid modified surgical techniques.
