Anterior sacral meningocele complicated by rectothecal fistula and rectorrhea: A Case report and review of the literature

Abstract

Background: Anterior sacral meningocele (ASM) is a rare congenital anomaly. It is characterized by herniation of the dura through a defect in the anterior sacrum. Rarely, however, it may extend to the rectal area through a rectothecal fistula with or without rectorrhea.

Case description: Here, we present a case of ASM associated with a rectothecal fistula and rectorrhea. Surgical closure of the ostium of the cyst through a posterior approach resulted in long-term improvement.

Conclusion: An ASM with both rectothecal fistula and rectorrhea is extremely rare.
