VEGA, Jorge  y  MATAMALA, Gonzalo. Cerebral salt wasting syndrome associated with Listeria monocytogenes encephalitis. Report of one case. Rev. méd. Chile [online]. 2013, vol.141, n.1, pp.104-108. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872013000100014.

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 rhom-boencephalitis 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 ofsodium 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.
