Intimal sarcomas of the pulmonary artery and aorta are rare entities with a poor prognosis. In many instances, pulmonary artery sarcomas are misinterpreted as acute or chronic pulmonary thromboembolism, whereas aortic intimal sarcomas are often misdiagnosed as protuberant atherosclerotic disease or intimal thrombus. Discernment of intimal sarcomas from these and other common benign entities is essential for the timely initiation of aggressive therapy. The most useful imaging modalities for assessment of a suspected intimal sarcoma include CT angiography, fluorine 18-fluorodeoxyglucose PET, and MRI. The authors discuss the clinical features, current treatment options, characteristic imaging findings, and underlying pathologic features of intimal sarcomas. The authors emphasize imaging discernment of intimal sarcomas and how their differential diagnosis is informed by knowledge of radiologic-pathologic correlation. The most reliable distinguishing imaging features are also emphasized to improve accurate and timely diagnosis. RSNA, 2021.
肺动脉和主动脉的内膜肉瘤是罕见的实体瘤，预后不良。在许多情况下，肺动脉肉瘤被误诊为急性或慢性肺血栓栓塞症，而主动脉内膜肉瘤常被误诊为突出的动脉粥样硬化性疾病或内膜血栓。将内膜肉瘤与这些和其他常见的良性实体瘤区分开来，对于及时开始积极治疗至关重要。评估疑似内膜肉瘤最有用的影像学检查方法包括 CT 血管造影、氟 18-氟脱氧葡萄糖 PET 和 MRI。作者讨论了内膜肉瘤的临床特征、当前的治疗选择、特征性影像学表现和潜在的病理特征。作者强调了影像学对内膜肉瘤的辨别，以及对放射病理相关性的了解如何为其鉴别诊断提供信息。还强调了最可靠的鉴别影像学特征，以提高准确和及时的诊断。
