The overwhelming majority of soft tissue masses encountered on routine imaging are incidental and benign. When incidental, the radiologist is usually limited to routine MR imaging sequences, often without contrast. In these situations, there are typical imaging features pointing to a single diagnosis or limited differential diagnosis. Although these imaging features can be helpful, many lesions are nonspecific and may require contrast administration, evaluation with other imaging modalities, follow-up imaging, or biopsy for diagnosis. This article will provide an overview of the most commonly encountered benign soft tissue masses along with some of their characteristic MR imaging features.
在常规影像学检查中遇到的绝大多数软组织肿块都是偶然发现的良性病变。在这种情况下，放射科医生通常只能使用常规的磁共振成像序列进行检查，而且通常不使用对比剂。在这种情况下，存在一些典型的影像学特征可以指向单一诊断或有限的鉴别诊断。尽管这些影像学特征可能会有所帮助，但许多病变是非特异性的，可能需要使用对比剂、其他影像学检查方法进行评估、随访影像学检查或活检才能明确诊断。本文将概述最常见的良性软组织肿块，并介绍其一些典型的磁共振成像特征。
