This case study shows a 45 years old lady who presented with Trigeminal neuralgia due to a Petroclival Meningioma which is a Skull Base Meningioma. This tumor is considered a very challenging tumor in neurosurgical circles. Many tumors are large, difficult to remove.

The video shows the preoperative scans and the surgical procedure known as anterior petrosal approach, dissection and removal of the tumor and postoperative MRI scans showing complete excision of the tumor. The patient recovered without additional cranial nerve deficits. She is doing well but continues to have facial pain for which she is under treatment. Removal of the tumor helped in preventing brainstem compression and development of hand and leg weakness due to continued tumor growth.
