Objectives Describe a case of an intravagal parathyroid adenoma. Case A 35‐year‐old male presented with symptomatic primary hyperparathyroidism and non‐localizing imaging studies. Intraoperative venous sampling revealed a substantial gradient within the right internal jugular vein. Repeat imaging identified an enhancing lesion in the right parapharyngeal space at the skull base. An intravagal parathyroid adenoma was discovered intraoperatively. Microdissection of the adenoma out of the nerve allowed preservation of laryngeal function and an appropriate drop in ioPTH. Conclusions Intraneural parathyroid adenomas are exceedingly rare. The clinical, radiologic, and histologic findings of an intravagal parathyroid adenoma in the post‐styloid parapharyngeal space are described. Laryngoscope , 131:453–456, 2021
