A case of mediastinal abscess in a hemodialysis patient

An asymptomatic mediastinal abscess was incidentally found in a 68-year-old male patient with a long history of hemodialysis. He had never had any symptoms but complained of chest pain only after the abscess ruptured into the right thoracic cavity. The abscess was discovered incidentally, when computed tomography was performed to determine the cause of his increasing ascites. Video-assisted thoracic surgery was performed to facilitate sufficient drainage and safe debridement. After the operation, we administered adequate antibiotics and continued irrigation of the thoracic cavity. The origin of his abscess was still unknown, but we have to consider that immunocompromised patients including those undergoing hemodialysis can develop severe infectious conditions even with minor causes. This case is clinically suggestive of the need to focus on the immunocompromised condition of hemodialysis patients. Furthermore, our case reveals video-assisted thoracic surgery to be a safe and less invasive procedure for patients in poor general condition.
