Gross-total resection of a suprasellar with recurrent cerebellopontine angle region craniopharyngioma by endoscopic far-lateral supracerebellar infratentorial approach: illustrative case

BACKGROUND: Craniopharyngiomas that rarely extend into the posterior fossa are treated with staged operations or combined approaches. The authors reported a patient undergoing gross-total resection of a suprasellar with recurrent cerebellopontine angle (CPA) craniopharyngioma using an endoscopic far-lateral supracerebellar infratentorial approach (EFL-SCITA). OBSERVATIONS: The patient was a 15-year-old boy who presented with headache and decreased vision that lasted for half a year. He previously received three surgeries related to CPA craniopharyngioma. Preoperative magnetic resonance imaging revealed a suprasellar with recurrent CPA craniopharyngioma. Gross-total resection of this suprasellar and CPA tumor was achieved through EFL-SCITA. All symptoms and signs were improved. There were no postsurgical complications except for mild facial paralysis. LESSONS: EFL-SCITA can be used not only for tumors in the posterolateral pontomesencephalon and ptero-clival-tentorial area but also for tumors in the suprasellar region with posterior fossa extension.
