Q fever represented as multiple pulmonary nodules: a case report

Q fever is an important zoonotic disease caused by the pathogen Coxiella burnetii, which is inhaled into the body through the respiratory tract leading to acute symptoms. Severe acute Q fever may result in complications, such as pneumonia, hepatitis, or myocarditis, and some patients may develop chronic Q fever after incomplete treatment. Local persistent C. burnetii infection may lead to chronic Q fever that often requires surgery and anti-infection treatment for several years, seriously endangering patient health and increasing the economic burden for families. The clinicians’ lack of awareness of the disease may be one reason leading to a delay in treatment. Here, a case of Q fever in a 53-year-old male patient, which was diagnosed by next generation sequencing and exhibited a distinct computed tomographic feature, is reported, with the aim of improving clinical knowledge of this disease. Following diagnosis, the patient was treated with 0.1 g doxycycline, orally, twice daily, and 0.5 g chloramphenicol, orally, three times daily, leading to improvement of symptoms and discharge from hospital.
