Abstract
|
|
|
|
Cholesterol granulomas are unusual, expansile benign lesions, which may produce symptoms from localized mass effect. It can develop in any portion of air cells within the temporal bone as a result of a lack of aeration and inadequate drainage, especially in the middle ear cavity followed by the mastoid process and the petrous apex. But huge cholesterol granulomas with extensive temporal bone destruction and intracranial extension are rarely reported. Recently we experienced a case of huge cholesterol granuloma with intracranial extension misdiagnosed as a intracranial tumor, such as schwannoma or meningioma in a 52-year-old female. After tumor removal, destroyed tegmen tympani was reconstructed with artificial dural materials and plates. We reviewed this case with relevant publishings in medical literature.
