A four-year-old girl presented in a comatose state with profound hypoglycemia that unmasked a craniopharyngioma, according to a case report published in the Journal of Neurosurgery: Case Lessons.
Emergency medical testing upon the patient’s admission revealed a capillary glucose level of 40 milligrams per deciliter, or 2.2 millimoles per liter. Officials noted that the child’s consciousness returned rapidly after an intravenous dextrose bolus was administered.
The patient had experienced progressive headaches and vomiting for four days prior to her arrival at the hospital, where she scored a six on the Glasgow Coma Scale. Medical staff initially attributed her low blood sugar to malnutrition caused by poor oral intake from vomiting. However, the recurrence of hypoglycemia within twenty-four hours prompted further clinical evaluation.
Medical teams performed a gross-total resection utilizing a pterional approach. Histological analysis subsequently confirmed an adamantinomatous craniopharyngioma.
Postoperatively, the patient’s hypoglycemia resolved entirely.
Separate pathological records from Frontiers in Surgery describe a separate diagnostic case involving a 53-year-old man who experienced a seven-year diagnostic pitfall. That patient was initially diagnosed with a Rathke’s cleft cyst in December 2017 after undergoing endoscopic endonasal transsphenoidal surgical resection. A reoperation 7.5 years after the initial surgery yielded a revised diagnosis of papillary craniopharyngioma following BRAF V600E testing and a review of the mixed tissue components.
Craniopharyngiomas account for five to ten percent of all pediatric intracranial tumors. Medical literature indicates that while endocrine dysfunction occurs in fifty to eighty percent of cases at the time of diagnosis, presentation with hypoglycemia remains exceptionally rare.
Unexplained pediatric hypoglycemia requires prompt endocrine evaluation and sellar imaging to rule out underlying structural intracranial pathology. Multidisciplinary management involving both neurosurgery and endocrinology teams is vital to achieving favorable clinical outcomes in these rare pediatric presentations.
The patient remained stable on her medication regimen following the complete removal of the lesion and the restoration of normal sellar and suprasellar anatomy demonstrated on postoperative computed tomography scans.
Clinical observations emphasize that healthcare providers must consider sellar-suprasellar masses when evaluating pediatric patients who present with severe and recurrent hypoglycemic episodes that do not correlate with standard nutritional deficits.
Early identification of secondary endocrine deficits such as central adrenal insufficiency prevents life-threatening metabolic complications in young children presenting with atypical neurological sentinel symptoms.
Medical teams continue to monitor pediatric cohorts to better understand the long-term metabolic profiles and treatment challenges associated with these epithelial tumors.
