ABSTRACT

Hyponatremia which is a very common electrolyte abnormality in hospitalized patients is defined as a plasma sodium concentration less than 135 mEq/L. Hyponatremia is generally caused by intravascular volume depletion, excessive salt loss and hypotonic fluid overload. It also can be caused by intravascular osmotic agent. Although most cases are mild and asymptomatic, acute severe hyponatremia can cause severe neurologic symptoms, such as seizures and coma. We report a rare case of severe hyponatremia induced by radiographic contrast agent.

Key words: Hyponatremia | Seizure | Radiographic contrast agent
