case_images: a: Chest radiograph (posterior-anterior view) showing right middle and lower lobe collapse (Figure 1b): Computed Tomography of the thorax showing an oval homogenously enhancing soft tissue density in right bronchus intermedius causing complete occlusion of right middle and lower lobe. (Figure 1c): Whole body F18-Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Low FDG uptake (SUVmax-3.5) was noted in an ill-defined lesion in right bronchus intermedius causing luminal narrowing and associated distal collapse (Figure 1d): 68Ga-DOTATATE scan showing intense uptake (SUVmax-50.15) in an ill-defined lesion in right bronchus intermedius causing luminal narrowing and associated distal collapse.

case_images: Chest radiograph (posterior-anterior view) showed right middle and lower lobe collapse [Figure 1a]. As a part of initial staging Whole body 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) imaging [Figure 1c] as well as 68Ga-DOTATATE scan was done, which showed low FDG uptake (SUVmax-3.5) in an ill-defined lesion in right bronchus intermedius causing luminal narrowing and associated distal collapse without any foci of distant metastasis [Figure 1b,1c]. An intense uptake was noted on 68Ga-DOTATATE PET-CT (SUVmax-50.15) suggestive of high SSTR expression at the site of primary [Figure 1d] as would be expected in a case of typical carcinoid with morphological features similar to those seen in the FDG PET/CT images without evidence of metastasis.
