Triphasic dysnatremia complicated by generalized convulsions following craniopharyngioma resection in a pediatric patient

Craniopharyngiomas are benign epithelial tumors arising from craniopharyngial duct. Although rare, these are the most common suprasellar, non-glial tumors in children constituting about 50% of all sellar / suprasellar tumors. The management of these tumors can be very challenging not only periopratively but also in postoperative phase as it can lead to extremes of dysnatremias ranging from central diabetes incipidus (CDI), syndrome of inappropriate anti diuretic hormone (SIADH) to cerebral salt wasting syndrome (CSWS). We present a triphasic sodium imbalance following craniopharyngioma resection complicated by generalized convulsions.
