Radiology showed a subcentimeteric colloid cyst at the foramen of monro. A transcallosal corridor was used to reach the foramen of monro, and the suprachoroidal access was adopted to uncover the colloid cyst and excise it completely preserving the deep veins.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The patient had uneventful recovery and radiology showed complete excision of the cyst.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Transcallosal approach, being minimally invasive, exploits the natural extra-axial corridor (interhemispheric) obviating the need for a cortical incision.
