Reversible posterior leukoencephalopathy syndrome after withdrawal of antipsychotic medication in the context of lithium intoxication.

ABSTRACT

OBJECTIVE: To report a case of reversible posterior leukoencephalopathy syndrome (RPLS) after withdrawal of antipsychotic medication in a patient with acute lithium intoxication. METHODS: Case report. RESULTS: A patient with schizoaffective disorder was admitted with lithium intoxication, rhabdomyolysis and acute renal failure. After withdrawal of psychotropic medication, she developed a significant increase in blood pressure - though to moderately hypertensive levels - and prolonged disturbance of consciousness with profound agitation. MRI revealed RPLS. Resumption of antipsychotic treatment resulted in significant drop of blood pressure and improvement. CONCLUSION: Acute withdrawal of antipsychotic medication may lead to rebound hypertension and development of RPLS, especially in the presence of lithium intoxication and renal dysfunction.
