description Multiple myeloma (MM) is a cancer characterized by the expansion of plasma cells in the bone marrow. Survival times of patients with MM have increased due to the development of novel therapeutic agents. We herein highlight three MM cases that had a poor prognosis despite treatment with novel therapeutic agents. Of note, all patients presented with hyperammonemia that led to a consciousness disorder. The outcome for patients with MM showing high levels of serum ammonia continues to be poor, even with the use of novel therapies. For such patients showing a consciousness disorder, hyperammonemia should be considered as a possible cause.
