Unexpected presentation of diabetes insipidus following pineal tumor resection: A case report

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 result following pituitary neurosurgery. contrast, surgical resection non-sellar does not commonly in CDI, with only few cases reported the literature. We report case 40-year-old man who presented transient CDI pineal papillary tumor via an occipital interhemispheric trans-tentorial approach. The underlying pathogenesis occurring post arising at distance from sella yet clearly understood, especially since there no evidence direct compression stalk. With regards our case, we hypothesize that restauration initial obstructive hydrocephalus might induce rapid intracranial pressure variation leading hemodynamics changes portal hypophyseal vascular system. Postoperative air entrapment sellar region also lead irritation This highlights may happen consequence and advocates for careful postoperative monitoring.
