Abstract

Bronchiolitis obliterans organizing pneumonia (BOOP) is a pulmonary disorder that exhibits various radiographic findings. It often shows bilateral, patched, or ground glass interstitial infiltrate, but a solitary nodular pattern rarely appears. We report a case of an 8-year-old boy suffering from BOOP that showed a single nodular pattern of the lung in the chest radiography. We conclude that when there is a solitary nodule discovered in the lungs of children or adolescence, the differential diagnosis must include BOOP.

Keywords: Bronchiolitis obliterans organizing pneumonia, Pulmonary solitary nodule

Figures and Tables

Fig. 1

Chest radiograph showed a round shaped mass like consolidation in the right lower lobe at hospital day 1.

Fig. 2

Chest computer tomography image showed a 3.5 cm sized mass with ground glass opacity, containing focal calcification in the right lower lobe.

Fig. 3

(A) The biopsy specimen showed aninflammation in the surrounding alveoli, with thickening alveolar walls with lymphoid cell infiltration (H&E, ×100). (B) Granulation tissue in the bronchiolar lumen, alveolar ducts, and some alveoli in polypoid shape (H&E, ×200).

Fig. 4

Follow-up chest radiograph, at 2 years later after the surgical excision, showed that the round shaped mass in the right lower lobe had completely disappeared. No relapse occurred.
