67Gallium scans in Löfgren's syndrome.

Comparison of 67Gallium scans of head and neck showed no significant difference in intensity of uptake between patients with Löfgren's syndrome and sarcoidosis patients with similar chest x rays having other modes of onset. Uptake was the same in the 12 white and 18 black patients studied. Thus, the increased bronchoaveolar lavage lymphocytosis which has been shown to be a feature of Löfgren's syndrome is not paralleled by gallium uptake. Gallium scores had no predictive value regarding outcome showing no significant difference between 13 patients who recovered within a year and 15 patients who developed chronic disease. The outcome was more favorable in white patients and in those whose onset was with Löfgren's syndrome.
