目的 :探讨慢性化脓性中耳炎胆固醇肉芽肿的发病机制 ,临床及影像学的诊断与鉴别。方法 :对 6例经手术和病理证实的、继发于慢性化脓性中耳炎的胆固醇肉芽肿患者的病例资料进行分析。结果 :胆固醇肉芽肿可与多种中耳疾病同时存在 ,MRI检查 T1 W与 T2 W皆为高信号。结论 :胆固醇肉芽肿的发病机制为中耳的其它疾病如胆脂瘤、硬化灶等导致的通气受阻 ,仅凭 CT及临床体征不能区别胆固醇肉芽肿与胆脂瘤 ,MRI对本病诊断有极大的价值。
Objective: To investigate the pathogenesis, clinical diagnosis and differential diagnosis of chronic suppurative otitis media with cholesterol granuloma. Methods: Six cases of pathologically confirmed cases of Cholesterol granuloma secondary to chronic suppurative otitis media were analyzed. RESULTS: Cholesterol granuloma was associated with a variety of middle ear diseases. Both T1 W and T2 W were high MRI signals. Conclusion: The pathogenesis of cholesterol granuloma is obstructed by other diseases of the middle ear, such as cholesteatoma and sclerosis. Ventilation caused by CT and clinical signs can not distinguish between cholesterol granuloma and cholesteatoma. Great value.
