目的 探讨隐蔽部位肺癌漏误诊的原因。方法 本组经手术病理证实隐蔽部位肺癌 10例 ,常规摄胸部正位像 ,有 6例加摄侧位像 ;所有病例均经CT扫描检查 ,平扫 6例 ,平扫加增扫 4例 ,在病灶或肺门区加 5mm薄扫。结果 本组病例常规X线检查发现原发病灶 1例 ,胸腔积液 3例 ;CT扫描显示病灶并明确诊断 9例 ,未显示病灶 1例。结论 ( 1)CT对隐蔽部位肺癌定位准确、并有助于其定性、定量分析。 ( 2 )高千伏摄影有助于减少隐蔽部位肺癌的漏诊。 ( 3 )常规摄胸部正侧位像并结合CT扫描是提高隐蔽部位肺癌诊断水平的关键 ,必要时应结合纤支镜检和MRI。
Objective To explore the causes of missed diagnosis of lung cancer in concealed sites. Methods In this group, 10 cases of lung cancer with concealed location were confirmed by operation and pathology. The chest image was taken routinely, and 6 images were taken as lateral images. All cases were examined by CT scan, plain scan in 6 cases, plain scan plus enhanced scan in 4 cases. Add a 5mm thin scan to the lesion or hilar area. Results The routine X-ray examination in this group of patients revealed 1 case of primary lesion and 3 cases of pleural effusion; CT scan showed lesions and 9 cases were diagnosed clearly, and 1 case showed no lesion. Conclusions (1) The location of lung cancer in concealed sites is accurate and helpful for qualitative and quantitative analysis. (2) High kV photography helps reduce the missed diagnosis of lung cancer in concealed areas. (3) Routinely taking a positive lateral image of the chest combined with a CT scan is the key to improving the diagnostic level of lung cancer in concealed sites. If necessary, it should be combined with fiberbronchoscopy and MRI.
