Differences in CT imaging signs between patients with tuberculosis and those with tuberculosis and concurrent lung cancer.

OBJECTIVE: The purpose of this study was to compare the differences in imaging features between patients with pulmonary tuberculosis (TB) alone and patients with TB complicated with lung cancer (LCA) as well as to investigate the diagnostic value of CT in these two groups. METHODS: In this retrospective study, 110 patients with confirmed TB admitted to the Second Affiliated Hospital of Hainan Medical University from March 2020 to April 2021 were collected and divided into TB+LCA group (50 cases, diagnosed with TB complicated with lung cancer) and TB group (60 cases, diagnosed with TB alone) according to actual diagnosis. The CT results of both groups were analyzed by the same group of physicians in a double-blind manner. The diagnostic value of CT for TB alone and TB complicated with lung cancer was calculated. The differences in CT imaging characteristics between the two groups were investigated. The differences in the structural characteristics of para-cancerous tissue between the two groups were analyzed. RESULTS: <0.05). CONCLUSION: CT has certain application value in differentiating TB alone from TB complicated with lung cancer, and there are many similarities in the imaging features of the two conditions. CT can be considered as a preliminary means of differential diagnosis of TB complicated with lung cancer, which is helpful to the primary screening diagnosis of lung cancer.
