Twenty cases of pulmonary metastases from pathologically proven stomach carcinoma were studies with specialreference to the clinico-radiological findings and the grades of cell-differentiation of stomach carcinoma. Theywere calssifed into five types based on the pattern of chest X-ray findings according to the reportedclassifications of metastatic pulmonary carcinoma. The radiological appearance of pulmoanry metastases formstomach carcinoma was didffferent from that of usual pulmonary metastatic cancers. The Type IV metastatic form(Type IV-Progressive increasing interstitial lung markings and then infiltration of pulmonary parenchyme with orwithout evidence of pleural effusion.) was most commonly seen in stomach carcinoma particularly in poorlydifferentiated cell type and more associates with respiratory symptoms than others.
