Presacral abscesses: percutaneous transperineal drainage with use of bone landmarks and fluoroscopic guidance.

Presacral abscesses developed in two men (aged 59 and 76 years) after abdominoperineal resection. Computed tomography was performed to demonstrate the distance from the abscess to the perineum and the distance of the abscess anterior to the sacrum. Then, lateral and anteroposterior fluoroscopy was performed to guide transperineal drainage catheter placement. No complications occurred, and clinical outcome was successful in both cases.
