Primary mesenchymal intrathoracic tumors are unusual. They can originate from the lung, the pleura, or the mediastinal structures. These sarcomas have protean, nonspecific imaging features. This pictorial essay illustrates a large number of these tumors, describes the plain film findings, and emphasizes the contribution of the new imaging modalities. The cross-sectional display and the high contrast resolution computed tomography (CT) and the ability to image vascular structures and chest wall with magnetic resonance (MR) allow excellent delineation of tumor extent and assessment of chest wall or vascular invasion. Early recognition of recurrence or metastases can be facilitated. In rare instances, the intrinsic characteristics of the tumor allow a specific diagnosis.
原发性胸内间充质肿瘤并不常见。它们可起源于肺、胸膜或纵隔结构。这些肉瘤具有多样的、非特异性的影像学特征。这篇影像文章展示了大量此类肿瘤，描述了X线平片表现，并强调了新型成像模态的作用。横断面显示以及高对比度分辨率计算机断层扫描（CT），还有磁共振成像（MR）对血管结构和胸壁成像的能力，能够很好地描绘肿瘤范围并评估胸壁或血管侵犯情况。有助于早期识别复发或转移。在罕见情况下，肿瘤的内在特征可作出特异性诊断。
