Two months ago, chest P-A showed heterogenous, hazy, streaky densities on both lower lung fields and a well-marginated homogenous squared shape of mass-like density on the right middle lung (Fig. 1).
Chest P-A, at admission, reveals much improved infiltrations on both lower lung fields and right middle lung, but newly developed lobulated round homogenous density with 4x4 cm in diameter at left hilar region.

After 2 months of anti-tuberculous drugs, the chest X-ray revealed much improved infiltrations on both lower lung fields and right middle lung, but with newly developed lobulated, round homogenous density, with 4x4 cm in diameter, at the left hilar region (Fig. 2).
The computerized tomogram of thorax reveals 5x5 cm-sized, round, mass with surrounding low density suggesting pulmonary artery aneurysm with thrombosis in left lung.

The computerized tomogram of thorax revealed 5x5cm-sized, round, mass with surrounding low density, suggesting PAA with thrombosis in left lung (Fig. 3).
The digital subtraction pulmonary angiogram reveals dilated left inferior pulmonary artery (indicated by arrow-heads) proximal to the obstructed pulmonary artery and well-preserved left upper lung (indicated by arrows).
