Bilateral nodular pulmonary tuberculomas simulating metastatic disease.

A 62-year-old lady presented with bilateral nodular lung opacities suspicious of metastatic disease on chest radiography and high-resolution CT. Histopathology, however, revealed caseating granulomas. The correct diagnosis of tuberculosis (TB) was confirmed when she responded clinically and radiologically to antitubercular treatment. TB should be considered in the differential diagnosis of bilateral nodular opacities which is the usual presentation of secondary malignancies of lung.
