We evaluated, the clinical findings, radiological evidences, operation technique, complications and outcome in third ventricle colloid cysts and assessed the most safe and easy surgical approach for the treatment. 11 cases of third ventricle colloid cyst who underwent transcallosal operation between 2009-2017 were analysed retrospectively. In 10 of these cases cyst was visualised through foramina monro and in nine of them cysts were easily removed. We additionally applied posterior inter fornicial approach to the 10th case. In the 11th case the cyst could not be visualised through foramina monro and was found to be burried in paranchyma between foramina monro and commissuria anterior. The cyst was removed through the incision performed to columna fornicis lying on the cyst. Up to our knowledge third ventricle colloid cyst at this location is not reported in literature. Transcallosal, transforaminal and interfornicial approach which enables total resection with low complication and reccurence rate can be estimated as the most reliable procedure.
