Abstract
- Cholesterol granuloma is a histological term used for the description of a tissue response to a foreign body such as cholesterol crystals. The pathogenesis of cholesterol granuloma is controversial. But three factors are thought to have an important role in its development: obstruction of ventilation, impaired drainage, and hemorrhage. It may arise from any portion of the pneumatized temporal bone. But huge cholesterol granuloma with intracranial and extradural extension has been rarely reported. Recently, we experienced a case of huge cholesterol granuloma with intracranial and extradural extension. The patient has never experienced chronic otitis media before. The cholesterol granuloma was successfully removed by transmastoid approach. So we report this case along with a literature review.
