 CEREBRAL SALT WASTING SYNDROME ASSOCIATED WITH  LISTERIA MONOCYTOGENES ENCEPHALITIS. REPORT OF ONE CASE

Hyponatremia is common in patients with severe neurological diseases and is often secondary to a syndrome of inappropriate antidiuretic hormone secretion (SIADH). However, in some patients, hyponatremia is due to cerebral salt wasting syndrome (CSWS). SIADH and CSWS treatments are opposite and misdiagnosis can lead to increased morbidity and  mortality. We report a 52 years old female with a  rhomboencephalitis caused by Listeria Monocytogenes (LM), ventriculitis and abscesses in cerebellum and brainstem. It was associated with hyponatremia, hypotension, increased natriuresis, hypouricemia, and low creatinine and blood urea nitrogen levels. Large amounts of sodium were needed and the condition persisted after hospital discharge. Hyponatremia is common in central nervous system involvement by LM, however we are not aware of  CSWS reports  of this condition.
