BACKGROUND
Malignant pleural mesothelioma (MPM) is an uncommon neoplasm. MPM occurs more frequently in patients born or living in certain villages of Turkey.
OBJECTIVES
We aimed to review radiological findings of MPM.
PATIENTS AND METHODS
We reviewed the CT findings in 219 biopsy-proven MPM patients admitted to our clinic between 1993 and 2008.
RESULTS
The most common CT findings included pleural thickening (n=197, 90%) classified as diffuse (n=138, 63%), nodular (n=49, 22%) and mass-type (n=16, 7%). Pleural effusion was found in 173 patients (79%), involvement of the interlobar fissures in 159 (73%), mediastinal pleural involvement in 170 (78%), volume contraction in 142 (65%), mediastinal shift in 102 (47%) and mediastinal lymphadenopathy in 54 (25%).
CONCLUSION
MPM may present with diverse radiological features. Pleural thickening and pleural effusion were the most frequent radiological findings. Thoracic CT scans might be assessed more cautiously in patients with environmental exposure to asbestos.
背景
恶性胸膜间皮瘤（MPM）是一种罕见的肿瘤。MPM在出生或生活在土耳其某些村庄的患者中更为常见。
目的
我们旨在回顾MPM的影像学表现。
患者和方法
我们回顾了1993年至2008年间入住我们诊所的219例经活检证实的MPM患者的CT表现。
结果
最常见的CT表现包括胸膜增厚（n = 197，90%），分为弥漫性（n = 138，63%）、结节性（n = 49，22%）和肿块型（n = 16，7%）。173例患者（79%）出现胸腔积液，159例（73%）出现叶间裂受累，170例（78%）出现纵隔胸膜受累，142例（65%）出现容积缩小，102例（47%）出现纵隔移位，54例（25%）出现纵隔淋巴结肿大。
结论
MPM可能表现出多种影像学特征。胸膜增厚和胸腔积液是最常见的影像学表现。对于有石棉环境暴露史的患者，胸部CT扫描可能需要更谨慎地评估。
