摘　　要：目的分析青石棉污染区恶性胸膜间皮瘤的CT表现特点,以提高诊断符合率。方法搜集大姚县医院2010年7月～2012年3月21例经临床及病理证实的恶性胸膜间皮瘤患者CT表现,行回顾性分析。结果 21例患者中,20例胸膜增厚,其中弥漫性增厚16例,结节状增厚4例;单纯胸腔积液1例,后经胸膜穿刺后胸膜弥漫性增厚。大量胸腔积液7例,中等1例,少量7例,无胸腔积液6例。其中,单侧胸腔积液13例,双侧胸腔积液2例。CT表现为胸膜增厚≥1.1cm,大部分>2.0cm,最大厚度为6.8cm,呈结节状、条片状或巨块状软组织肿块,经增强扫描有明显强化。结论石棉污染区恶性胸膜间皮瘤典型CT表现为胸膜增厚、肿块、胸腔积液,并伴有胸膜斑、冰冻纵隔、胸壁侵犯。Objective To analyze CT characteristics of malignant phural mesothelioma （MPM） in the crocidolite-contaminated area, in order to improve its diagnostic accordance rate. Methods CT manifestations of 21 patients with MPM proving by both clinic and pathological tests from July 2010 to March 2012 in People′s Hospital of Dayao County were retrospectively analyzed. Results Among 21 patients, there were 20 cases with pleural thickening including 16 cases of diffuse thickening, 4 cases of nodular thickening, and 1 case of simple pleural effusion with diffuse thickening after thoracentesis. 7 cases were in great quantity of hydrothorax, 1 case was in moderate, 7 cases were in mild, and 6 cases were without fluid. The number of patients with unilateral pleural effusion was 13 cases, and the bilateral were cases. CT displayed that pleural thickening was no less than 1.1 cm, most of them were over 2.0 cm, and the maximum one was 6.8 cm, which were shaped in nodular, stripy or massive soft tissues, and it showed reinforce obviously by enhanced CT. Conclusion The typical CT manifestations of MPM in crocidolite-contaminated area are pleural thickening, mass, and pleural effusion, accompanying with pleural plaque, congealed mediastinum and invasion of thoracic wall.
