Chest CT scan may be helpful in the diagnosis of carcinoid tumor. On high-resolution CT scan of the chest, peripheral pulmonary carcinoid tumor is characterized by a solitary and round [[pulmonary nodule]] with a lobulated margin, whereas bronchial carcinoid tumor is characterized by a single well-defined, round or ovoid, hilar or perihilar [[mass]] with marked homogenous enhancement. On CT scan of the neck, thymic carcinoid tumor is characterized by a mass with heterogeneous attenuation.<ref name=thymicCT> Thymic carcinoid tumour.

Overview

Chest CT scan may be helpful in the diagnosis of carcinoid tumor. On high-resolution CT scan of the chest, peripheral pulmonary carcinoid tumor is characterized by a solitary and round pulmonary nodule with a lobulated margin, whereas bronchial carcinoid tumor is characterized by a single well-defined, round or ovoid, hilar or perihilar mass with marked homogenous enhancement. On CT scan of the neck, thymic carcinoid tumor is characterized by a mass with heterogeneous attenuation.
