Cholesterol granuloma is the most common primary lesion of the petrous apex. Management of petrous apex cholesterol granuloma has evolved in recent years from primary surgical treatment to conservative observation. In this article, a case of spontaneous resolution of a petrous apex cholesterol granuloma is described. To the authors' knowledge, this is the first known report of spontaneous involution of a petrous apex cholesterol granuloma. Radiographic differential diagnosis of petrous apex lesions and the natural history of cholesterol granulomas are discussed.
