CT
Peripheral Pulmonary Carcinoid Tumour HRCT Chest
Findings on CT scan suggestive of peripheral pulmonary carcinoid tumor include:[1]
- Most are discovered as an incidental rounded solitary pulmonary nodule.
- The size at diagnosis can vary but usually reported to be range around 10-30mm.
- Many have lobulated margin with an average Hounsfield value on post contrast imaging at around 50.
- Imaging features are often non specific and tissue diagnosis is essential in determining diagnosis.
Bronchial Carcinoid Tumour HRCT Chest
Findings on CT scan suggestive of bronchial carcinoid tumor include:
Central lesions are usually seen as:
- A single hilar or perihilar mass which is usually well-defined, round or ovoid.
- Can be of any size but typically range ~2-5 cm.
- There is often marked homogeneous contrast enhancement due to high vascularity.
- Calcification (usually eccentric) can occur but is not a common feature.
Thymic Carcinoids
On CT scan thymic carcinoids usually have heterogeneous attenuation.[2]
