摘　　要：目的:分析胸膜间皮瘤的螺旋CT征象特点,并探讨PET/CT对胸膜间皮瘤影像学诊断的辅助补充价值。方法:回顾性分析自1999年2月至2006年6月间经组织细胞学证实的23例胸膜间皮瘤患者螺旋CT及7例患者的PET/CT检查征象。结果:23例胸膜间皮瘤患者中,良性7例,恶性16例。局限性结节样胸膜增厚9例,良性7例,恶性2例;14例弥漫性胸膜增厚均为恶性。应用PET/CT检查的7例患者中,排除手术可行性5例。结论:CT能很好地显示胸膜病变的部位、形态、范围及与周边组织的关系,而PET/CT可更好地鉴别病变的良、恶性,及是否伴有远处转移,对恶性病例的分期更准确,对临床治疗有重要的指导作用。Objective： To study the CT and PET/CT features of pleural mesothelioma and the value of CT and PET/CT imaging in the diagnosis of the disease. Methods ： We retrospectively analyzed the spiral CT images of 23 patients and PET/CT images of 7 patients with pleural mesothelioma, all histologically confirmed. Results： Of the 23 cases detected by spiral CT, 7 were benign and 16 malignant; local nodular pleural thickening was found in 9 cases, 7 benign and ：2 malignant; diffuse pleural thickening was observed in 14 cases, all malignant. Of the 7 cases diagnosed by PET/CT, 5 were excluded from surgery. Conclusion： CT imaging helps determine the location, shape, extent of the pleural lesion and its relation to the surrounding tissues, while PET/CT is better in the differentiation of pleural mesothelioma and staging of malignancy, and therefore plays an important guiding role in the treatment of the disease.
