目的：探讨原发性肺类癌MSCT表现，以提高对该病的认识。方法收集病理证实的肺类癌12例，回顾性分析其病理分类及MSCT表现。结果典型类癌8例，非典型4例；中央型5例，周围型7例。所有病例均为单发，术后均未见淋巴结转移。肿块呈分叶状9例，其中中央型3例、周围型6例；7例气道阻塞性表现，其中5例为中央型、2例周围型。动态增强扫描，类癌表现为延迟强化明显，平均最大强化40 HU。结论原发性肺类癌周围型较中央型多见，MSCT可以更好地显示病变征象，肺类癌多为分叶状肿块，动态强化以延迟强化明显均匀强化，肿块内可有坏死或钙化，多直接或间接累及气道，同时伴有远侧肺野阻塞性表现。
目的：探討原髮性肺類癌MSCT錶現，以提高對該病的認識。方法收集病理證實的肺類癌12例，迴顧性分析其病理分類及MSCT錶現。結果典型類癌8例，非典型4例；中央型5例，週圍型7例。所有病例均為單髮，術後均未見淋巴結轉移。腫塊呈分葉狀9例，其中中央型3例、週圍型6例；7例氣道阻塞性錶現，其中5例為中央型、2例週圍型。動態增彊掃描，類癌錶現為延遲彊化明顯，平均最大彊化40 HU。結論原髮性肺類癌週圍型較中央型多見，MSCT可以更好地顯示病變徵象，肺類癌多為分葉狀腫塊，動態彊化以延遲彊化明顯均勻彊化，腫塊內可有壞死或鈣化，多直接或間接纍及氣道，同時伴有遠側肺野阻塞性錶現。

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 conifrmed by pathology were collected and retrospectively analyzed in the aspects of their pathological classiifcation and MSCT (Multi-Slice Computerized Tomography) features. Results Of all the 12 cases, 8 were identiifed as typical carcinoids and 4 atypical carcinoids;5 were conifrmed 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 calciifcation inside the lesions, and direct or indirect involvement with bronchus, accompanied with obstruction in the distal pulmonary ifeld.
