The severe symptoms of neurologic and psychiatric disorders accompanying this condition are not sufficiently disclosed in the literature. Most often CPM develops on infusion therapy and forced correction of hyponatremia. The complexity of diagnosis and the lack of certain algorithms for the management of this category of patients cause a high frequency of disability, persistent neurological and psychiatric symptoms, and lethal outcomes.The aim was to present and analyze clinical picture of psychosis in CPM on the example of non-Hodgkin’s lymphoma case report. Patient and method: clinical analysis of disorders in 14-years old patient with diagnosis of non-Hodgkin’s lymphoma.Results: clinical polymorphism of psychotic features, catatonic disorders, neurological symptoms at the end stage and development of psychosis associated with CPM during cytotoxic treatment.
