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

Findings on neck CT scan suggestive of thymic carcinoid tumor include:

  • Mass with heterogeneous attenuation[1]
