| 摘 要： | 目的探讨外耳道胆脂瘤(EACC)的特征性高分辨率CT(HRCT)表现。资料与方法回顾性分析经病理证实的38例EACC患者(40耳)的HRCT征象。结果 40耳EACC均表现为外耳道内密度不均的软组织影,其中30耳呈实性致密影,10耳软组织内可见含气征;7耳软组织内见可疑骨碎片影。骨性外耳道19耳呈烧瓶样扩大,18耳全程扩大;5耳仅下壁受累,35耳多骨壁受累,其中33耳下壁受累,19耳各壁均受累;25耳残余骨壁边缘光整,15耳边缘不规则;28耳鼓室盾板变钝或消失。30耳累及鼓室,9耳累及乳突;9耳部分听小骨受压吸收、破坏;11耳面神经管受累,其中乳突段5耳,鼓索神经小管4耳,鼓室段2耳;8耳颞下颌关节受累;1耳外半规管受累;21耳伴发乳突炎症。乳突呈气化型31耳,混合型8耳,板障型1耳。结论 HRCT有助于定性诊断EACC,并可清晰显示其范围及邻近结构受累情况,有助于临床选择相应的治疗方案。 |

| Abstract: | Objective To investigate the HRCT characteristic of external auditory canal cholesteatoma(EACC). Materials and Methods HRCT findings of 38 patients(40 lesions)with EACC confirmed by pathology were retrospectively analyzed. Results Heterogeneous soft tissues were found in the external auditory canal(EAC). Thirty lesions showed solid soft tissues and 10 lesions contained air density. Intramural bone fragments were found in 7 cases. The whole bony EAC showed enlarged in 18 cases, the medial EAC enlarged like f... |
