Adipsic diabetes insipidus secondary to craniopharyngioma resection

Adipsic diabetes insipidus is an infrequent disease which may be associated with craniopharyngioma. It may be secondary to the tumour's extension, as well as to resection of the mass. We present the case of a 24-year-old woman with a history of delayed puberty and hypothyroidism, but no prior study reports. She consulted due to a headache with warning signs associated with altered visual acuity. Brain MRI was performed which showed signs of a non-adenomatous lesion with suprasellar and hypothalamic extension. Following transcranial surgery, she developed diabetes insipidus criteria, with absence of thirst documented during the hospitalisation. The histopathological findings confirmed the diagnosis of craniopharyngioma. The patient was treated with desmopressin and received recommendations regarding rehydration according to the quantification of losses, with electrolyte stabilisation.
