Chest computed tomography revealed pneumonia and a lung abscess was suspected in the lower lobe of the left lung (Fig. 1).
(A) Wedge-shaped patchy dense shadows in the lower lobe of the left lung, with air bronchogram sign inside the region; inhomogeneous enhancement in the lesion on an enhanced scan, with multiple non-enhanced small cystic shadows; patchy shadows supplied by pulmonary artery from the left lower lobe are visible in the enhanced scan, associated with a slightly thin pulmonary artery, drainage of the left lower vein back to the left atrium, and no narrowing of the pulmonary vein. (B) Strip-like high-density shadows in the double pulmonary apex and lingual segment of the upper lobe of the left lung; unobstructed trachea and main bronchus, and obvious narrowing of the opening in the lower lobe of the left lung; normal size of the double hilus of the lung; slightly left shift of the heart, without abnormalities in size and morphology; and no presence of lymph node enlargement in the mediastinum. No abnormalities are observed in the pleura, ribs, or soft tissues of the chest wall.

These were speculated to be congenital malformations (Fig. 2A and B).

The diameter of the left bronchus was found to be reduced and a previous pulmonary hemorrhage was observed (Fig. 3).
(A) The size of the left lung lobe is approximately 11.5 cm x 10 cm x 5 cm, and the surface is uneven, showing an abnormal grayish black color. (B) A section of the lung lobe is grayish brown, packed with some capsule cavities of different sizes, and the maximum diameter is approximately 2.0 cm.

Gross pathologic examination of the lung tissue revealed dilation of the bronchia and blood vessels (Fig. 4A and B).
(A) Gross pathological examination of the lung tissue showing bronchiectasis, chronic inflammatory mucosal membrane, and fibrosis of the perivascular interstitium. (B) The interstitium of the alveoli has significant hyperemia, the septum is thickened, and pulmonary bullae are observed.

Hemorrhage and fibrinoid exudation were observed on the pathologic slice (Fig. 5A and B).

At a follow-up visit in January 2018, we performed a chest x-ray examination, and the results were normal (Fig. 6).
