We present a case of a small lung cancer that had developed in the lung peripthery engulfing a bulla and showing a mass with a cavitary area at the center on the high resolution CT (HRCT) image. It was difficult to make a differential diagnosis between lung cancer and tuberculoma. Longitudinal reconstruction of HRCT images helped us to understand the distribution of an air-space in the mass, which was continuous to the adjacent lung. A contrastenhanced magnetic resonance (MR) study gave additional information on the vascularity of the mass and helped to rule out tuberculoma.
