CT in diagnosis of solitary pulmonary nodules

Objective To study the diagnostic value of CT in solitary pulmonary nodules. Methods CT characteristics of 111 cases of solitary pulmonary nodules were retrospectively analyzed. Results In the 111 cases, there were 80 cases of lung cancer (25 cases of squamous cell carcinoma, 42 cases of adenocarcinoma, 5 cases of small cell undefferentiated carcinoma, 1 case of large cell undefferentiated carcinoma, 7 cases of alveolar cell carcinoma) and 1 case of lung metastasis of rectal adenocarcinoma. The diameter of lesions was 1.5-4 cm with an average of (3.10±0.77) cm. In the 30 cases of benign lesions, there were 8 cases of tuberculosis, 6 cases of hamartoma, 2 cases of mycosis, 6 cases of inflammatory pseudotumor, 4 cases of chronic nonspecific inflammation, 2 cases of inflammation granuloma, 1 case of abscess, and 1 case of globular atelectasis. The diameter of lesions ranged from 0.8 cm to 4 cm with an average of (2.47±0.94) cm. Conclusion CT is the first choice in the diagnosis and differential diagnosis of solitary pulmonary nodule.
