Sixth Nerve Palsy from Cholesterol Granuloma of the Petrous Apex

Herein, we report a patient who had an isolated sixth nerve palsy due to a petrous apex cholesterol granuloma. The sixth nerve palsy appeared acutely and then spontaneously resolved over several months, initially suggesting a microvascular origin of the palsy. Subsequent recurrences of the palsy indicated a different pathophysiologic etiology and MRI revealed the lesion at the petrous apex. Sur...

CASE REPORT Lobulated Petrous Apex Cholesterol Granuloma Treated with Infracochlear and Transsphenoidal Approaches

404 Petrous apex cholesterol granulomas are relatively rare lesions. They are usually unilocular and treated with simple fenestration. However, lobulated lesions require total removal of debris inside the cysts. Herein, we report a first case with a lobulated petrous apex cholesterol granuloma. The lesion extended from cerebello-pontine angel to the clivus. It was lobulated and contained debris...

Endoscopic Endonasal Resection of Cholesterol Granuloma of the Petrous Apex
