This controversy stems from overlapping clinical and laboratory findings and an inability to assess the volume status of these patients. Objectives:To present a case of a cerebral salt wasting syndrome secondary to a bacterial mengitis and to emphasize the difficulty to assess the diagnosis. Case report: A 51-year-old male admitted to the ICU for a severe bacterial meningitis who developed, four days later, hyponatremia associated with hypovolemia due to a renal salt wasting. Clinical and biological parameters were collected;electrolytes balances and salt clearances were calculated to best investigate this hydroelectrolytic disorder. Patient's volume status and improvement after fluid and sodium replacement highly suggests the diagnosis of a cerebral salt wasting syndrome. Conclusion: A thorough analysis of this case showed that occurrence of hyponatremia and renal salt wasting after brain agression is not univocal underlying the fact that the diagnosis of cerebral salt wasting should be assessed only after a careful examination of the different determinants of the hydroelectrolytical balance.展开更多

This paper reports the case of a 13 year-old boy who underwent surgery for a suprasellar tumour and, immediately after surgery, developed a cerebral abscess, persistent diabetes insipidus (DI) as well as cerebral salt wasting syndrome (CSWS). The early onset of CSWS following DI has been associated with a poor prognosis and increased mortality. In cases in which these abnormalities coexist, the increased polyuria secondary to the rise in natriuresis associated with CSWS might be erroneously interpreted as a sign of poor control of the DI, thereby leading to therapeutic mistakes. Treatment basically consists of restoring electrolytes and the joint administration of desmopressin and fludrocortisone.展开更多
