Abstract

Craniopharyngiomas are tumors originating from the infundibular stalk, extending to the parasellar and suprasellar region, thereby conferring multiple risks of this region. In particular, hypothalamic and pituitary damage related to its natural history as well as treatment effects of craniopharyngiomas substantially affect life expectancy and quality of life. Here, we describe an adult patient presenting with polyuria, memory, and visual field impairment secondary to concurrent craniopharyngioma and intraventricular glioma. He was treated with surgical resection with postoperative course notable for hypothalamic-pituitary dysfunction, including central hypothyroidism, central adrenal insufficiency, arginine vasopressin deficiency (AVP-D, formerly diabetes insipidus) with loss of sense of thirst, and hypothalamic hypothermia. The adipsia, combined with memory dysfunction, challenged the management of constant fluctuations in his sodium (129–168 mEq/L), with ultimate treatment through vasopressin repletion, fixed fluid intake, strict urine output monitoring, and close counseling of the patient and his caregiver. This case exemplifies the complexity of the endocrine care of patients with craniopharyngiomas and highlights the need for step-wise algorithms in the treatment of hypothalamic deficiencies such as adipsia.
