67Ga accumulation in pulmonary lesions associated with bleomycin toxicity

The radionuclide, gallium-67, accumulates in a wide variety of neoplastic and inflammatory lesions. Diffuse bilateral lung localization of 67Ga occurred in two cases of interstitial pneumonitis associated with bleomycin therapy. Clinical symptoms and laboratory evaluation of pulmonary status correlated with scintigraphic studies in these two patients, while discrepancies between scintigraphic and roentgenographic findings were observed.
