title: Case report: recurrent pseudocyesis in a male patient with psychosis, intermittent hyponatremia, and polydipsia.
abstract: This report describes a case of recurrent pseudocyesis in a man with psychosis, intermittent hyponatremia, and polydipsia. The pseudocyesis was documented on three separate occasions coinciding with bouts of acute hyponatremia and rapid weight gain stemming from ingestion of large amounts of water. In contrast, no pseudocyesis was elicited during intervening normonatremic states. Abdominal distention, neuropsychological deterioration, and worsening of psychosis during acute hyponatremia are considered as contributing factors to the pseudocyesis.
