Primary chest wall neoplasms are uncommon and comprise a heterogeneous group of lesions that may be challenging to classify and diagnose. These tumors may be primary or secondary, malignant or benign, and arise from cartilaginous/osseous structures or soft tissues. The role of magnetic resonance (MR) imaging in the evaluation of chest wall tumors continues to expand given its superior soft tissue contrast relative to computed tomography. MR imaging can facilitate differentiation of neoplasms from normal chest wall structures and other disease processes due to infection and inflammation, and can fully characterize abnormalities by demonstrating the various internal components of complex lesions. It is important that radiologists be able to identify key features of primary chest wall neoplasms on MR imaging to provide focused differential diagnoses and guide patient management.
原发性胸壁肿瘤并不常见，由一组异质性病变组成，分类和诊断可能具有挑战性。这些肿瘤可以是原发性或继发性的，恶性或良性的，起源于软骨/骨结构或软组织。由于磁共振（MR）成像相对于计算机断层扫描具有 superior soft tissue contrast，其在胸壁肿瘤评估中的作用不断扩大。MR成像可以促进肿瘤与正常胸壁结构以及由感染和炎症引起的其他疾病过程的鉴别，并通过显示复杂病变的各种内部成分来充分表征异常。放射科医生能够在MR成像上识别原发性胸壁肿瘤的关键特征，以提供有针对性的鉴别诊断并指导患者管理，这一点很重要。
