ABSTRACT
El Quiste Glioependimario es un tumor extremadamente raro y excepcionalmente pocos casos han sido reportados; se caracterizan por una cavidad cerrada, con una capa de tejido de epitelio ependimario o una mezcla de tejido ependimario y epitelio coloideo, con un lumen relleno por líquido cefalorraquídeo. Presentamos el caso de un paciente manejado en el servicio de neurocirugía de la Universidad de Cartagena con esta patología.

The true incidence of intracranial arachnoid cysts is unknown because many may be asymptomatic throughout life. However, with the advent of CT and MRI the frequency of the diagnosis of arachnoid cyst has significantly increased. In adults they represent 9% of all the arachnoid cysts while in paediatric population this percentage reaches 15%.The various surgical options for treating suprasellar arachnoid cysts [SSAC] include craniotomy with fenestration or marsupialization of the cyst, cystoperitoneal shunt and percutaneous ventriculocysto-cisternostomy. Ten patients with SSAC were operated on in our institution since 1992. The aim of our work consists of describing the clinical manifestations, the radiological features and the different surgical methods to treat SSAC. The patients ranged in age from one month to 33 years [mean age = 8 yrs]. The signs and symptoms are referable to the size of the cyst. All patients with SSAC underwent preoperative CT, cisternography or MRI. In 7 patients, marsupialization of the cyst was performed; in 5 patients, a cystoperitoneal shunt was placed and ventricuhocysto-cisternostomy performed in only 2 patients. Five patients were operated more than one time undergoing two different methods of surgery

A 53 year-old woman presented a recurrent bifrontal headache of 2 years duration and bilateral progressive visual disturbance. The clinical and neurological examination showed a bilateral feet adactyly and bitemporal hemianopsia. The brain MRI demonstrated a Rathke's cleft cyst. The patient was operated by a transnasal endoscopic approach. It seems that this unusual association has never been described before.
Mulher de 53 anos com história recorrente de cefaléia com duração de 2 anos bilateral e progressiva, acompanhada de distúrbios visuais. O exame clinico e neurológico mostrou uma adactilia dos pés e hemianopsia bitemporal. A ressonância nuclear magnética cerebral mostrou um cisto de Rathke. A paciente foi operada por via transnasal endoscópica. Aparentemente esta é a primeira vez que esta associação é descrita na literatura.

Estudamos retrospectivamente quatro pacientes com cisto de bolsa de Rathke. Chamamos a atençäo para a apresentaçäo clínica e para o tratamento destas lesões. Todos ocorreram em pacientes do sexo feminino. Os sintomas predominantes foram amenorréia, cefaléia e déficit visual. Revisamos várias séries publicadas de cistos de bolsa de Rathke. Concluimos que o tratamento cirúrgico é ainda a melhor conduta e que a via transesfenoidal é a abordagem mais indicada
