Rectalepidural fistula complicating Crohn's enterocolitis.

A previously unreported complication of a patient with Crohn's enterocolitis and internal fistulation is presented. The patient presented with meningeal signs in the lumbosacral region, fever, and sepsis. Computerized axial tomography revealed air in the epidural space, and a presumptive diagnosis of rectalepidural fistula was made. Surgical management included a diverting end sigmoid colostomy and presacral drainage.
