AbstractA 91-year-old woman was brought to our hospital with altered consciousness. Blood tests showed an increased ammonia level of 468 μg/dL and a normal liver function. Chest computed tomography showed massive right pleural effusion with loculation. We immediately performed chest drainage using two drainage tubes. The pleural effusate pH was 8.5. We diagnosed her with right empyema leading to hyperammonemia and initiated ampicillin/sulbactam therapy. However, she developed progressive renal failure and died on the third day. Empyema caused by urease-producing bacteria can lead to hyperammonemia. This is the first report of hyperammonemia due to empyema in the English literature.
