Twenty cases of pulmonary metastases from pathologically proven stomach carcinoma were studies with special reference to the clinico-radiological findings and the grades of cell-differentiation of stomach carcinoma. They were classified into five types based on the pattern of chest X-Ray findings according to the reported classifications of metastatic pulmonary carcinoma. The radiogical appearance of pulmonary metastases from stomach carcinoma was different 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 or without evidence of pleural effusion.) was most commonly seen in stomach carcinoma particularly in poorly differentiated cell type and more associated with respiratory symptoms than others.
