VILLALBA MARTINEZ, Gloria et al. Abordaje endoscópico de los quistes gliales pineales sintomaticos. Rev. argent. neurocir. [online]. 2009, vol.23, n.4. ISSN 1850-1532.

Objetive. Sympotomatic glial pineal cyst (GPC) are unfrequent. Surgical management of these cysts is not consensed. In the literature there are 18 cases reported treated by endoscopic approach. The purpose of this study is to contribute with our experience to the endoscopic treatment of the GPC. Materials and Methods. Between 1999 and 2004, five patients with GPC underwent an endoscopic third ventriculostomy (ETV) and cyst fenestration. We have used a rigid endoscope, with neuronavegation system in the cases without hydrocephalus. Results. In the follow-up period ranged from 6 months to 4 tears we have reported: clinical resolution in four cases and cyst size decrease in all cases. All the ETV have been patent. There was not perman ent morbility and not surgery related death. Discussion. An agreement doesn't exist in the literature about the better treatment of the surgery or by stereotaxy as the best treatment. There are great differences in the surgical management between the 18 endoscopic cases reported in the literature, and also in relation with our cases. Conclusion. The ETV with endoscopic cyst fenestration is an efficient treatment due to the low morbidity and the effectiveness in the treatment of the GPC with or without hydrocephalus. The open surgery (specially with the endoscope assisting microneurosurgery) wolud be a second choice technique, and the stereotactic surgery must be abandoned.
