ABSTRACT

Objective: to make a bibliographical review in purpose of an infrequent case of cystic dilatation of the conus ventriculus terminalis. Description Female patient of 34 years old, who consults for invalidating anal pain and rectal tenesmus. The MRI shows an image compatible with cystic dilatation of ventriculus terminalis. Intervention The treatment consists in simple wide laminectomy; midline microsurgical myelotomy and marsupialization with subaracnoidal space. Following myelotomy and fenestration a significant reduction in size of the cyst was seen in MRI. Conclusion: The patient clinical response was good in relation with her initial situation (invalidating anal pain), only persists the parestesis in the right dermatomas L5-S1. This last symptom requires medical co-adyuvance (CBZ). Radiological evolution of the lesion was excellent. To 5 years only post-surgical changes are evident.
