“…This was first reported by Tack et al 11 who described enlarged and beaded segmental and subsegmental pulmonary arteries with peripheral TIB resulting from intravascular tumor emboli of desmoplastic small round cell tumor up to the centrilobular arteries. Similar cases have been reported in pancreatic adenocarcinoma, 12 leiomyosarcoma, 13 and chondrosarcoma. 14 Pulmonary tumor thrombotic microangiopathy is a distinct specific condition characterized by fibrocellular intimal proliferation of the small pulmonary arteries and arterioles in patients with metastatic carcinoma, where tumor emboli do not directly occlude affected vessels but induce both local activation of coagulation and fibrocellular intimal proliferation, which eventually lead to stenosis or occlusion of the vessels.…”

As the bronchioles have a strategic position between the airways and the alveolar structures, they are at a site where disorders of many origins may develop, including infections, inflammatory and/or fibrosing processes of immune, occupational, environmental, tumoral, and iatrogenic origin, which may result in predominant bronchiolitis and/or organizing pneumonia. This etiologic variety results in many distinct entities and syndromes, common or rare, with new or renewed faces such as bronchiolocentric interstitial pneumonia or organizing pneumonia primed by radiation to the breast.

“…As for uterine sarcomas, there has been a single case presenting a “tree-in-bud” pattern for pulmonary metastases, but PLS of uterine sarcoma has not been reported previously [11] . Because of these rare pathways of metastatic sarcoma, we cannot rule out the metastases from these findings.…”

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.
