Abstract

Pulmonary lymphatic involvement of sarcomas is an extremely rare form of metastases. We report the computed tomography (CT) features of pathologically confirmed pulmonary lymphatic involvement from metastatic uterine sarcomas. The CT illustrated smooth or nodular thickenings of the interlobular septa and bronchovascular bundle. Moreover, ground-glass opacity along the interlobular septa was also detected. These findings suggest that lymphatic involvement has diagnostic value for detecting this rare form of metastatic sarcomas. We also discuss possible differential diagnoses in this case and review previous cases reporting pulmonary lymphatic involvement in metastatic sarcomas. To the best of our knowledge, this is the first report describing pulmonary lymphatic involvement in metastatic uterine sarcomas. Pulmonary lymphatic spread of sarcomas is a rare form of metastatic sarcomas, but it should be considered when these findings suggesting lymphatic involvement are detected on CT.
