Thigh phlegmon as a first sign of a ruptured pelvic presacral abscess caused by ileal diverticulum fistula: A case report

Abstract

Highlights Ileal diverticulum rarely causes pelvic abscess. Pelvic abscess rarely causes thigh phlegmon. Rupture of presacral abscess to extra-pelvic site carries high mortality. Intrapelvic pathology has to be considered in patients with thigh phlegmon.
