M. Salman Ali, MD; Fernando Vale, MD; Medical College of Georgia at Augusta University
Linear incision followed by retrosigmoid craniotomy was performed. Tumor was internally debulked. Tumor dissection away from petrous bone and tentorium. 7/8 complex was preserved along with lower cranial nerves. Tentorium was coagulated and cut and removed along with supratentorial portion of the tumor. 4th cranial nerve identified in the depth along with 3rd nerve. Trigeminal nerve could be seen medial to the tumor and 6th nerve in the ventral aspect. Gross total resection was achieved.
