Male Pelvis: Everything but the Prostate! (2025)-T8-CGU01-2025

Video Transcription

Video Summary

The transcript summarizes several radiology talks on male genitourinary imaging, focusing on MRI and emergency assessment. One speaker reviews penile MRI anatomy (corpora cavernosa, corpus spongiosum, tunica albuginea) and proper positioning/protocols (multiplanar T1/T2, diffusion, and contrast for tumors). MRI is highlighted for penile trauma to distinguish hematoma from true fracture (tunica tear) and to identify vascular causes of priapism (e.g., traumatic arteriocavernosal fistula via MRA). MRI also evaluates penile prostheses, ideally imaged flaccid and inflated, and inflammatory conditions like Peyronie’s disease (nonenhancing low-signal plaques). For tumors, MRI helps stage squamous cell carcinoma—most common and often HPV-associated—by assessing invasion of spongiosum/urethra (T2) and cavernosal involvement through tunica disruption (T3), with adjacent organ invasion as T4. Imaging location can suggest alternative diagnoses (urothelial carcinoma, sarcoma, metastases).<br /><br />A second talk details penile implants (malleable vs inflatable three-piece) and complications: sizing errors (buckling, “floppy glans”), migration (distal, lateral, proximal, medial “crossover”), mechanical failure (aneurysm, fracture), reservoir/pump malposition, infection, fistula, and hematoma.<br /><br />A scrotal imaging talk emphasizes that intratesticular masses are usually malignant (germ cell tumors in young men; lymphoma >60), while epididymal masses are usually benign; many incidental lesions <10 mm (especially <5 mm) are benign and can be surveilled. MRI aids in segmental testicular infarction and fibrous pseudotumor diagnosis.<br /><br />An emergency talk reviews CT cystography for bladder rupture (intraperitoneal requires surgery; extraperitoneal often catheter drainage), urethral injury classification/management, and imaging of penile fracture with ultrasound or MRI to guide repair.
