To describe the normal CT imaging–depicted anatomy of the superficial perineal pouch.

US guidance was used for injection of up to 400 mL of iodinated contrast material into the space between the dartos and Buck’s fascia at each penile shaft of five fresh cadavers. MDCT was performed of the pelvis and perineum after the injection. All images were reconstructed coronally and sagitally and reviewed to evaluate the extent of the space. Two cadavers, who were injected with blue ink mixed contrast material, were dissected to confirm the CT findings.

The injected contrast material surrounded the corpus spongiosum, copora cavernosa and contents of the scrotum. It extended in front of the anus posteriorly and to the potential space between the superficial fascia and the anterior abdominal muscles anterosuperiorly. The superficial perineal pouch filled with contrast material was limited by Colles’ fascia posterosuperiorly, not extended to the inferior margin of the urogenital diaphragm. There was no communication between the superficial perineal pouch and the pelvic extraperitoneal space.

This findings show that the superficial perineal pouch is a relatively large, potential and closed space. Clinical implications are that acute idiopathic scrotal edema, Fournier's gangrene, scrotal hematoma and hematoma induced by penile fracture progress and are confined to this space.
