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.[1][2]
CT
Peripheral Pulmonary Carcinoid Tumor High-Resolution CT Chest
Findings on high-resolution CT scan suggestive of peripheral pulmonary carcinoid tumor include:[2]
- Discovered as an incidental solitary and round pulmonary nodule
- Size at diagnosis can vary but ranges between 10-30 mm
- Lobulated margin
Bronchial Carcinoid Tumor High-Resolution CT Chest
Findings on high-resolution CT scan suggestive of bronchial carcinoid tumor include:
- Well-defined single hilar or perihilar mass
- Round or ovoid in shape
- Variable in size but typically ranges between 2-5 cm
- Marked homogeneous contrast enhancement due to high vascularity
- Calcification (usually eccentric) can occur
Thymic Carcinoid
On CT scan of the neck, thymic carcinoid tumor is characterized by a mass with heterogeneous attenuation.[1]
