Craniopharyngeal canal, morning glory disc anomaly and hypopituitarism: what do they have in common?

A 14-year-old girl with a history of mid-line defects, basal encephalocele and morning glory disc anomaly presented with untreated growth hormone deficiency, pubertal delay and hypothyroidism. She was found to have a large craniopharyngeal canal based on MRI scan. Craniopharyngeal canal is an uncommon condition that has not been well described in the pediatric population. Consideration of craniopharyngeal canal in the differential diagnosis for basal encephaloceles and understanding its presentation can impact medical decision making and follow-up for patients.
