Intraventricular cavernous malformation associated with medullary venous malformation.
We reported a case of cavernous malformation (CM) associated with medullary venous malformation in the same area. The CM was located in the trigone of the lateral ventricle in the dominant hemisphere and drained into the longitudinal caudate vein of Schlesinger via deep medullary veins. By a transsylvian transventricular approach, the CM was totally removed with successful preservation of the medullary venous malformation. This approach is available for trigonal lesions, especially in cases with enlarged inferior horn. We stress that CM removal can be conducted with preservation of the adjacent medullary venous malformation.
