A 69-year-old male kidney transplant patient was admitted to an external healthcare center with complaints of weight loss, cough and hemoptysis that had started 6 months earlier. A computed tomography revealed a cavity in the upper segment of the left lung lower lobe, and a PET-CT revealed a high SUV-max uptake. Upon application to our hospital, the same symptoms were identified, along with R. equi growth observed in Bronchoalveolar Lavage and blood cultures. The patient was followed up with mechanical ventilator as intubated. Acinetobacter baumannii grew in the con trol ETA (endotracheal aspirate) culture on the 6th day of hospitalization, and he died subsequently on the 23rd day of hospitalization from colistin-induced nephrotoxicity. To the best of our knowledge this is the first case in which R. equi cavitary pneumonia has been seen together with R. equi bacteremia in our country.eninfo:eu-repo/semantics/openAccessArticle113132137113488510.5505/respircase.2022.54366
