摘要
到目前為止，在文獻上仍然很少有人對細支氣管肺泡癌的電腦斷層表徵做過系統性的整理。我們回顧了23個電腦斷層的細支氣管肺泡癌的病例，觀察其電腦斷層的各種影像學特徵，並加以分析整理。在我們的病例中，單一型的腫瘤有17例，其中呈小葉狀邊緣的佔82%，邊緣不規則呈星形徵象的佔59%，呈尾巴徵象者佔82%，呈不均勻密度的佔41%，呈假空洞化的佔41%，此外，有一例較大的腫瘤，其中央有真的空洞化。全部17例單一型腫瘤均位於肺野周邊。瀰漫型的腫瘤有6例，其中呈瀰漫性多發性細小結節的有2例，呈肺葉實質化的有4例。在4例肺葉實質化的病例中，呈空氣支氣管圖像的有3例，呈空氣圖像的有4例，呈均勻低密度的有1例，呈不均勻密度的有1例，呈電腦斷層血管攝影徵象的有1例，呈肺葉體積減少的有2例。另外，我們觀察到一個骨骼轉移的病人，其骨骼轉移在電腦斷層上為明顯的成骨性轉移。

There are few serial discussions in the literature about CT scan features of bronchioloalveoar carcinoma. We reviewed the CT scan features of 23 cases of bronchioloalveolar carcinoma. We had 17 solitary type bronchioloalveoar carcinoma, of which 82% showed lobulated border on CT scan, 59% showed irregular margins forming a “star sign”, 82% showed “tail sign”, 41% showed heterogeneous attenuation in the tumor, and 41% showed “pseudocavitations”. We noticed true central cavitation in a larger solitary tumor. All of the 17 solitary type tumors were located in peripheral lung fields or subpleural areas. We had 6 cases of diffuse type bronchioloalveolar carcinoma, within which 2 cases showed diffuse multiple nodules, and 4 cases showed lobar consolidation. Among 4 cases of lober consolidation, 3 cases showed air bronchogram, 4 cases showed air alveologram, 1 case showed homogeneous low attenuation, 1 case showed heterogeneous attenuation, 1 case showed heterogeneous attenuation, 1 case shoed “CT angiogram sign”, and 2 cases showed volume reduction of the consolidated lobe. We also found a patient with bone metastasis from bronchioloalveolar carcinoma, which showed prominent osteoblastic appearanceon CT scan.
