Contralateral Transcingulate Approach for Periventricular Cavernous Malformations Presenting With Intraventricular Hemorrhage or Subarachnoid Hemorrhage

The contralateral transcingulate approach provides a steeper angle of exposure for the resection of lesions in the wall of, or protruding into, the ventricle. This approach may offer unique benefits in select cases, when carefully planned with consideration of key anatomic landmarks, over the transcallosal or transcortical approaches when indicated after careful anatomic consideration of the lesion.
