Recurrent infrasellar clival craniopharyngioma

Summary

The patient is a 44-year-old man who underwent resection of a posterior nasopharynx tumor 12 years earlier via left lateral rhinotomy approach. The final pathological analysis indicated the tumor was a craniopharyngioma, and the patient subsequently underwent focal radiation. The patient returned to medical attention complaining of dysequilibrium. A neurologic exam was nonfocal. Magnetic resonance imaging revealed a clival mass, separate from the sella turcica, with imaging characteristics concerning for chordoma or primary bone tumor (Fig. 1). The lesion was resected via an endoscope-assisted endonasal transsphenoidal approach, with gross total resection achieved. Intraoperatively, the mass was noted to erode through the posterior nasopharynx, without extension superiorly into the sella or posteriorly through the clival dura (i.e., lesion was infrasellar). The final pathological results indicated the tumor was adamantinomatous craniopharyngioma.
