[Isomorphism of primary and secondary tumors of bone in radiographs (author's transl)]Radiologic findings of spread of malignant lymphoreticular processes in the lungs and their response to cytostatic therapy (author's transl)].

Retrospective evaluation of follow-up series of chestfilms of 30 patients suffering from malignant lympho-reticular processes of the lungs and treated with cytostatic drugs. Among 130 changes of form there were foci of infiltration which could be recognized as due to malignant lymphoreticular deposits. They were large zones of shrinking, stripey scars, perivascular densities with vague contrours, an accent on reticular basic pulmonary structure, widening of interlobar septa and stripey shadows in the shape of plate atelectases. During the changes developing in time, the tumor adhered to a certain degree to its primary pattern of spread. Combinations of different types of foci appear to be signs of the severity of the disease.
