Abstract:
Objective To investigate the differences of CT features for different subtypes of pulmonary neuroendocrine tumors (PNETs).Methods CT imaging data of 41 patients with PNETs and 5 patients of lung cancer with neuroendocrine differentiation confirmed by pathology were analyzed retrospectively,and the differences in CT features among pathological subtypes were explored. Results Among the pathological subtypes of 41 PNETs,the statistical differences in the CT features including vascular invasion,the metastatic lymphadenopathy in the hilus and mediastinum were found(P<0.05).However,no differences were found in other imaging findings (lesion location,spiculation,bronchial invasion,atelectasis and obstructive pneumonia,and pleural effusion or thickening)among the subtypes (P>0.05).Among those subtypes PNETs and lung cancer with neuroendocrine differentiation,the differences in tumor size,vascular invasion,and metastatic lymphadenopathy in the hilus and mediastinum were also found (P<0.05).However,no differences were found in other imaging findings (P>0.05).In addition,there were differences in tumor size among different enhancement types and different metastastic presences in the lung or outside of the chest (P<0.05).Conclusion CT shows certain differences among the different subtypes of PNETs,which may be helpful for the differential diagnosis but not specific.
