Abstract

We report the case of a 66-year-old man with dental infection who presented to our emergency department complaining of a 3-month medical history of chest pain and productive cough, in association with malaise, fever, weight loss and anaemia. His chest radiograph showed a nearly total opacification of the right hemithorax and chest ultrasound findings were suggestive of empyema, subsequently confirmed by a chest CT. The patient started appropriate treatment. A follow-up chest CT performed to rule out bronchopleural fistula revealed a large lung abscess. The patient had the final diagnosis of a giant lung abscess, which was initially thought to be an empyema because of the clinical and radiologic similarities with this entity. The initial misdiagnosis led to prompt percutaneous drainage of the lung abscess in addition to antibiotherapy and respiratory physiotherapy with a good final outcome, which suggests the efficacy of this approach in similar cases.
