On chest x-ray, bronchial carcinoid tumor is characterized by the presence of round or oval opacities with sharp and notched margins, whereas thymic carcinoid tumor often demonstrates focal areas of necrosis or punctate calcifications.

X-ray features of bronchial carcinoid tumor are often non specific.
On chest x-ray, bronchial carcinoid tumor is characterized by round or oval opacities from 2-5cm with sharp and notched margins.
Associated hilar or perihilar mass maybe present.
Associated airway compression with pulmonary atelectasis may be also seen in some cases.^[1]
Pleural effusions are unusual but can occur with postobstructive pneumonia.
Approximately one-fourth of cases present in the periphery as an asymptomatic solitary pulmonary nodule.

Thymic carcinoid tumor typically manifests as large masses with a propensity for local invasion.
On chest x-ray, thymic carcinoid tumor is characterized by focal areas of necrosis or punctate calcifications.^[2]
