Pleural effusion is a clinical problem that has many causes, with hemothorax being one of them. Computed tomography readily characterizes pleural fluid with determination of the attenuation value, helping to distinguish hemothorax from other types of effusion. Herein, we report the case of a 67-year-old man with end-stage renal disease in which a high-density pleural effusion due to residual contrast media was misinterpreted as hemothorax. Radiologists should consider the possibility of contrast media retention when interpreting a high-density pleural effusion in patients with end-stage renal disease. Recognition of this entity is crucial to avoid misdiagnosis, which might lead to unnecessary testing or procedures.
胸腔积液是一个有多种病因的临床问题，血胸是其中之一。计算机断层扫描通过测定衰减值能够轻松对胸腔积液进行特征描述，有助于将血胸与其他类型的积液区分开来。在此，我们报告一例67岁终末期肾病男性患者的病例，其因残留造影剂导致的高密度胸腔积液被误诊为血胸。放射科医生在解读终末期肾病患者的高密度胸腔积液时应考虑造影剂潴留的可能性。认识到这一情况对于避免误诊至关重要，误诊可能会导致不必要的检查或操作。
