| Objective To explore the clinical features, laboratory examination results and imaging characteristics of thoracopulmonary type paragonimiasis patients misdiagnosed as pulmonary tuberculosis, analyze the causes of misdiagnosis, and provide evidence for clinicians to make differential diagnosis. Methods Clinical information of 18 patients with thoracopulmonary type paragonimiasis misdiagnosed as pulmonary tuberculosis who were admitted in Beijing Friendship Hospital, Capital Medical University from February 2016 to February 2019 were collected and analyzed.
