Objective To investigate CT characteristics of pulmonary tuberculosis by analyzing the reasons of misdiagnosis in 35 patients with pulmonary tuberculosis. Methods The patients in this study included 19 men and 16 women, with ages ranging from 18 to 79 years old. Chest CT scans were performed in all patients. The CT films were reviewed retrospectively by two senior radiologists and were correlated with pathologic findings. The misdiagnosing reasons were analyzed. Results Misdiagnoses as lung cancer were made in 29 cases, pneumonia in 4 cases, and other diseases in 2 cases. The lesions on CT films appeared as nodules and masses in 14 cases, pulmonary segmental and lobar shadows in 19 cases ,and hilar and mediastinal masses in 2 cases. Conclusion The main causes of misdiagnosis for pulmonary tuberculosis are atypical radiological appearance on CT films, inadequate visualized lesions, and lacking of combination of CT findings with that of chest radiography.
