Abstract
Objective: To explore CT features of pulmonary small cell neuroendocrine tumor. Methods: Imaging findings of 28 patients with pathologically confirmed pulmonary small cell neuroendocrine tumor were retrospectively analyzed, all patients underwent plain CT and contrast enhanced CT examinations. Results: There were 18 cases were central type. Mass or nodule in hilar or medisatina side and thick Bronchial wall were seen in 18 (88%). Hilar and mediastinal lymphadenopathy were seen in 15 (83%). Mass and lymph nodes were significantly heterogeneous enhancement with contrast enhanced CT examination. 10 cases fell into peripheral carcinoma without features of CT. Conclusion: Pulmonary small cell neuroendocrine tumor is mainly as bronchial wall thickening with mass, the tumor has homogeneous density with hilar and mediastinal lymph nodes.
