回顾20例胸部子片X光照片和CT横断面图像肺上沟肿瘤患者。对比分析认为用CT图像诊断肺上沟肿瘤意义在于进一步了解邻近结构如肋骨、椎体、脊神经根、纵隔和臂丛受累情况要优于普通X线检查。CT提供的资料及研究结果表明:前、中斜角肌脂肪间隙模糊,臂丛神经根周围脂肪内淋巴结增大。提示肿瘤向腋窝及上肢浸润。
A retrospective review of 20 cases of chest radiographs and CT cross-sectional images of patients with upper lobe tumors. Comparative analysis believes that the use of CT images in the diagnosis of supraapical tumors is of significance in understanding the adjacent structures such as ribs, vertebral bodies, spinal nerve roots, mediastinum, and brachial plexus more than the ordinary X-ray examination. The data provided by CT and the results of the study showed that the fat spaces between the anterior and middle scalene muscles are blurred and the lymph nodes around the brachial plexus roots are enlarged. It suggests that the tumor has infiltrated into the armpits and upper limbs.
