摘要

本研究主要目的為探討肺部疾病於電腦段層掃描（CT）中各種表徵。疾病包括肺癌，非癌症疾病及肺結核。本研究共有三十一位病人，其中十五例為肺癌、十六例為非癌症疾病（其中包括十例肺結核），並評估各種疾病是否具有下列CT中的表徵:塊質（或大的小結）、堅實、病變內的空洞化、病變內的壞死、小結性濁斑、肺葉或分節之分佈、延伸至縱隔腔、包圍大血管、縱隔腔淋巴腺病及肋膜間積水等。所得到的結果以Fisher's Exact test 來比較肺癌和非癌症疾病的關係以及肺癌和肺結核的關係。結果顯示，塊質 (或大的小結）及壞死較容易出現於肺癌，另外堅實及空洞化較常出現在非癌症疾病及肺結核的病例，而小結性濁斑於肺結核較具特異性。所得到的結論為CT對於肺部惡性腫瘤及非癌症疾病（尤其對肺結核而言）的鑑別非常重要。

The purpose of this study is to review the com-puted tomography(CT)appearances of the lung dis-eases including carcinoma, non-cancerous dis-eases and pulmonary tuberculosis. Thirty one patients with 15 cases of lung carcinoma and 16 cases of non-cancerous diseases(including 10 cases of tuberculosis) were evaluated based on the CT findings of mass(or large nodule), consolidation, intralesional cavitation, intralesional necrosis, nodular opacities, lober or segmental distribution,
extension to the mediastinum, encasement of great vessels, mediastinal lymphadenopathy and pleural effusion. The results were compared between lung carcinoma and non-cancerous disease and between lung carcinoma and tuberculosis using Fisher's Exact test. Our results show that mass(or large nodule) and necrosis are more common in lung car-cinoma while consolidation and cavitation are more frequently found in non-cancerous diseases and tuberculosis. Nodular opacities are more specific for tuberculosis. We conclude that CT is important in differentiating lung malignancy and non-tumoral lung diseases, especially tuberculosis.
