Background: Colloid cysts are not common brain lesions and account for 0.2-2.0% of all brain lesions. Transcallosal, transforaminal approach is a safe route and the most direct path to excise third ventricular colloid cyst, without dependence on hydrocephalus. Aim: To assess the surgical outcome of patients with colloid cysts of the anterior third ventricle treated by the transcallosal, transforaminal approach. Patients and Methods: Seventy-eight patients operated by the above approach over a period of 20 years were analyzed. A pre- and postoperative neurological assessment was done in all the patients. Neuro-cognitive evaluation of corpus callosum function was done in the last 20 patients. Computer tomography scan of the brain was done in all patients pre- and postoperatively. Results: Clinical features of raised intracranial pressure without localizing signs were the commonest presenting feature in 52 (66.7%) patients. Hydrocephalus was present in 65 (83.3%) patients. All patients underwent the transcallosal, transforaminal approach, and total excision of the lesion was achieved in 77 patients and subtotal in 1. Four patients required a postoperative shunt for acute hydrocephalus. There was no incidence of postoperative disconnection syndrome. In two patients, there was recurrence of the lesion after 2 and 6 years, respectively. Two patients died in the postoperative period. Conclusion: Colloid cyst is surgically curable. Early detection and total excision of the lesion can be a permanent cure with low mortality and minimum morbidity, when compared to the natural history of the disease. The limited anterior callosotomy does not result in disconnection syndromes or behavioral disturbance.
