[Bleomycin-induced lung changes in the roentgen picture].

Amongst 25 patients treated with Bleomycin for squamous epitheliomas, irreversible pulmonary fibrosis was observed in four cases and reversible fibrosis in two others. The radiological changes in five patients consisted of linear interstitial shadows and one patient showed nodular shadowing. By means of lung biopsies, these findings were related to the pathological changes. Problems in the differential diagnosis of these radiological findings are discussed.
