| 摘 要： | 目的 探讨颅骨胆脂瘤的CT表现，以提高其诊断正确率。方法 回顾性分析15例经手术病理证实的颅骨胆脂瘤的CT表现。结果 病变均为单发，14例起源于板障，1例发生于颅缝间。CT平扫均表现为颅骨局限性膨胀性骨质破坏，边缘可见硬化边，7例突破颅骨内外板，边缘呈火山口样改变。11例密度不均匀，其中6例病灶内存在斑点状钙化，1例以脂肪密度为主，2例以水样密度为主，2例以等密度为主；4例病变密度均匀。2例行增强扫描，均表现为轻度强化。多平面重组(MPR)、VR图像可立体直观显示骨质破坏的形态及程度。结论 颅骨胆脂瘤的CT表现具有特征性，结合后处理技术可提高诊断正确率。

| Abstract: | Objective To investigate the CT characteristics of skull chlesteatoma,and explore its diagnostic accuracy.Methods CT characteristics of 15 skull chlesteatomas confirmed by surgery and pathology were retrospectively analyzed.CT plain scan were performed in all the patients,while extra enhanced CT scan was done in 2 cases.Results On the CT images,all cases were solitary.14 cases originated from intradiploe,and one case from skull suture.Extensive destruction of the skull with hard margin was found in 15 patie... |
