Image-guided transphenoidal drainage of a cholesterol granuloma of the petrous apex in a child.
Cholesterol granulomas of the petrous apex are well-described lesions that originate from chronic obstruction of the air cells in the petrous pyramid. Intracranial surgery, associated with multiple potential complications, has been the salutary action to treat this entity with only two reports of endoscopic drainage of a cholesterol granuloma of the paranasal sinuses. We present the first pediatric patient to be treated by not only endoscopic drainage, but also by the incorporation of computer-assisted image-guided surgery to minimize risk of injury to structures adjacent to the posterior wall of the sphenoid sinus.
