Résumé : | Background: Neuroendocrine dysfunction is a common complication of several neurosurgical conditions. In particular, central diabetes insipidus (CDI) can occur subsequent to traumatic brain injury, subarachnoid hemorrhage, cerebral tumors or as a result of a complication following pituitary neurosurgery. In contrast, surgical resection of non-sellar tumors does not commonly result in CDI, with only a few cases reported in the literature. Case description: We report the case of a 40-year-old man who presented a transient CDI following surgical resection of a pineal papillary tumor via an occipital interhemispheric trans-tentorial approach. The underlying pathogenesis of CDI occurring post resection of tumors arising at a distance from the sella is not yet clearly understood, especially since there is no evidence of direct compression of the pituitary stalk. With regards to our case, we hypothesize that restauration of the initial obstructive hydrocephalus might induce a rapid intracranial pressure variation leading to hemodynamics changes of the portal hypophyseal vascular system. Postoperative air entrapment in the sellar region might also lead to irritation of the pituitary stalk. Conclusion: This case highlights that CDI may happen as a consequence of pineal tumor resection and advocates for a careful postoperative monitoring. |
