Non-Hodgkin's lymphoma with pulmonary infiltrates mimicking miliary tuberculosis

Miliary infiltrates observed on chest films in non-Hodgkin's lymphoma are extremely rare. We report a case with pulmonary infiltrates mimicking miliary tuberculosis associated with prominent eosinophilia and elevated IgE levels. The levels of circulating eosinophils correlated with disease activity as they transiently returned to normal after effective chemotherapy in a short period. However, the patient developed acute respiratory failure due to the rapid progression of the disease even with intensive chemotherapy. We emphasize that small nodular shadows appear to be a sign of the rapid progression of the disease and a poor prognosis.
