Abstract
Medial temporal cavernous malformations can involve transgression of eloquent parenchyma. For a tentorium-abutting temporal cavernous malformation, the supracerebellar transtentorial corridor is a suitable approach with minimal parenchymal insult. Using dynamic and gravity retraction, lighted bipolar forceps and suction, and stereotactic navigation, this trajectory provides a minimally invasive corridor. The patient in this case has a medial temporal cavernous malformation, with the lesion abutting the tentorial leaflet. The cavernous malformation is accessed and removed in a piecemeal manner. Complete removal of the lesion is achieved. The patient remained neurologically stable after the procedure. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.
