Pituitary Mass Presenting As Rapid Onset Hyponatremia
A 43-year-old male presented to an outside hospital emergency department for lower abdominal pain, nausea, and vomiting. At that time, patient’s evaluation was benign, except for a finding of a sodium of 133. Abdominal imaging was performed and was unremarkable, and the patient was sent home without a diagnosis. Two days later, however, the patient re-presented with acute altered mental status. He was found to have a sodium of 112 and a head CT showed a large pituitary mass. With this presentation, we will discuss differential diagnosis of hyponatremia, pathophysiology of pituitary tumors, and perioperative management of both.
