case_images: Computed tomography (CT) scan of the chest. There is a new, mildly lobulated subpleural nodule in the right upper lobe measuring 1.6 x 1.6 cm.

case_images: After five years, a follow-up CT scan revealed a new 1.6 cm subpleural nodule in the right upper lobe (RUL) (Fig. 1).
case_images: Positron emission tomography (PET) scan. There are a 1.6 cm right upper lobe mass measuring with a maximum standardized uptake value (SUV) of 11.4 and a hypermetabolic right hilar node with maximum SUV of 8.2.

case_images: Further investigations using positron emission tomography (PET) imaging showed hypermetabolic activity in the RUL lesion and right hilar node (Fig. 2).
case_images: Navigational bronchoscopy with the right upper lobe (A) and right lower lobe (B) views. The targeted right upper lobe mass was located in the distal part, and the image could not be obtained effectively using the bronchoscopy. The proximal view of the right upper lobe was clear with no mass (A). An incidental finding of endobronchial tissue obstructing the right lower lobe superior subsegment was observed (B).

case_images: Navigational bronchoscopy and endobronchial ultrasound (EBUS) revealed two tumors: the RUL lesion and an incidental finding of endobronchial tissue obscuring the right lower lobe (RLL) superior subsegment (Fig. 3).
