Abstract:
The patient was in his 70s. He was addmitted to our hospital because of obstructive pneumonia for 3 months. Chest computed tomography( CT) showed a nodule at the base of the right B8, obstructing the basal branch, with consolidation of the peripheral lung. Bronchoscopy revealed the right basal trunk obstruction by a tumorous lesion. FDG-PET showed heterogeneous FDG uptake at the right hilum and the lower lobe suggesting malignancy, and a thoracoscopic right lower lobectomy was performed. Pathology showed a granulation-like nodule and a brown oval foreign body incarcerated in the peripheral bronchus, which was later revealed to be a peanut, and no obvious malignant findings were observed.
