Colloid cysts are congenital benign lesions, associated with more aggressive clinical and radiological picture in children than in adults. We present our experience in management of five pediatric patients with colloid cyst of the anterior third ventricle. They have an excellent chance of surgical cure, or they can be devastating and even fatal, if not recognized on time and treated. Material and methods:
Five pediatric patients (aged 16 years or less) who were surgically treated for a colloid cyst, between 1987 and 2011 were analyzed. The clinical features included raised intracranial pressure in all five cases, of which one patient was brought unconscious with decerebrate posturing. Computed Tomography (CT) scan of the brain was done in all patients. The density of the lesion, enhancement with contrast and the presence of hydrocephalus were analyzed. Four patients underwent a detailed postoperative neurological assessment.
Results:
Three patients underwent the transcallosal-transforaminal approach and total excision of the lesion. One patient underwent revision of the pre-existing ventriculoperitoneal shunt. One patient who was brought in an unconscious state, an external ventricular drain was inserted and she was ventilated. She died four hours after the admission. On follow up, none of the three patients who underwent the transcallosal-transforaminal approach had disconnection syndromes or behavioral disturbances.
Conclusion:
Colloid cysts in children are rarer and more aggressive than their adult counterparts. It is surgically curable. Early detection and total excision of the lesion is a permanent cure with minimum morbidity, when compared to the natural history of the disease. The limited anterior callosotomy does not result in disconnection syndromes or behavioral disturbance.
Key words: Colloid cyst, pediatric, transcallosal-transforaminal, anterior third ventricle, disconnection syndrome.
