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.
