Syndrome of Inappropriate Secretion of Antidiuretic Hormone (SIADH) Associated with Cerebellar Stroke: Case Report and Literature Review

11-34 % of acute ischemic stroke patients will develop hyponatremia. Hyponatremia in stroke is usually of the hypoosmolar type caused either due to the Syndrome of Inappropriate Secretion of Anti Diuretic Hormone (SIADH) or Cerebral Salt Wasting Syndrome (CSWS). In Ischemic strokes hyponatremia secondary to SIADH is mostly seen in strokes involving anterior circulation where the hypothalamic-pituitary axis is directly involved. In this report, we present SIADH in a patient with cerebellar stroke and discuss the possible mechanisms of development of SIADH in cerebellar stroke.
