A rare case of ectopic recurrence of a craniopharyngioma diagnosed 17 years after initial presentation

Abstract

Ectopic recurrence of craniopharyngioma 17 years after initial diagnosis is exceedingly rare in pediatric neuro-oncology. Only 23 cases of ectopic recurrence in children with craniopharyngioma are described in the literature with a median time to recurrence of 3 years. We describe a patient diagnosed at 5 years of age, presenting with neck pain and ataxia 17 years after diagnosis. Her original follow-up care was fragmented and included surveillance imaging for 10 years after surgery and endocrine management of panhypopituitarism. Rare, extremely late relapse of this tumor highlights the importance of extended multidisciplinary follow-up care that includes neuro-oncologists in a late-effects/survivorship program.
