A novel cause of emergent hyperammonemia: fungemia and meningitis.

Among etiologies of hyperammonemic emergencies, infection must be considered in certain clinical contexts, particularly among immunocompromised individuals. Although is known to be urease-producing, to our knowledge it has not previously been described as a cause of hyperammonemia in patients. We report an immunocompromised man with acute on chronic kidney disease with hyperammonemic crisis due to meningitis and fungemia. It is important to be aware of as a possible cause of hyperammonemia.
