Abstract：Objective To study the MSCT features of primary pulmonary carcinoid tumors so as to enhance the understanding of the disease. Methods 12 cases of primary pulmonary carcinoids confirmed by pathology were collected and retrospectively analyzed in the aspects of their pathological classification and MSCT (Multi-Slice Computerized Tomography) features. Results Of all the 12 cases, 8 were identified as typical carcinoids and 4 atypical carcinoids; 5 were confirmed to be the central type and 7 the peripheral type. All the cases were solitary and no local lymphatic nodes metastases were found postoperatively. Among 9 cases with lobulated lesions, 3 were the central type and 5 the peripheral type. Among 7 cases with the features of obstructive bronchus, 5 were the central type and 2 the peripheral type. The contrast-enhanced CT examination revealed the features of pulmonary carcinoid tumors as obvious delayed enhancement and the mean maximum enhancement value was 40HU. Conclusion The peripheral type was more commonly seen in primary pulmonary carcinoid tumors than the central type. MSCT demonstrated an excellent capability for better displaying the pathologic changes of lesions. Pulmonary carcinoid tumors could be characterized as lobulated nodules mostly, obvious delayed enhancement and even enhancement, possible presence of necrosis or calcification inside the lesions, and direct or indirect involvement with bronchus, accompanied with obstruction in the distal pulmonary field.
