All but one of the reported cases was found after multiple neck explorations. To the best of our knowledge, we report the first case of nonsupernumerary ectopic intravagal parathyroid identified at primary exploration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>A 17\u2010year\u2010old girl with primary hyperparathyroidism and nephrolithiasis was referred with a sestamibi scan reporting a left lower parathyroid adenoma. No eutopic parathyroid tissue was identified during full exploration of the left side of the neck. Exploration of the carotid sheath revealed a fusiform swelling of the vagus nerve at the level of the carotid bifurcation. Longitudinal incision of the vagal perineurium revealed a 7\u2010mm parathyroid adenoma, which was enucleated. The patient recovered uneventfully, with normalization of serum calcium, parathyroid hormone (PTH), and normal vocal cord function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We believe that this is the first reported case of nonsupernumerary intravagal parathyroid adenoma resected at initial exploration. The vagus nerve is a rare location for a parathyroid adenoma, but one that should be considered, even during primary exploration. \u00a9 2015 Wiley Periodicals, Inc. <jats:italic>Head Neck<\/jats:italic> <jats:bold>37:<\/jats:bold> E200\u2013E204, 2015<\/jats:p><\/jats:sec>","DOI":"10.1002\/hed.24068","type":"journal-article","created":{"date-parts":[[2015,4,13]],"date-time":"2015-04-13T14:31:29Z","timestamp":1428935489000},"source":"Crossref","is-referenced-by-count":15,"title":["Ectopic intravagal parathyroid adenoma"],"prefix":"10.1002","volume":"37","author":[{"given":"Jurstine","family":"Daruwalla","sequence":"first","affiliation":[{"name":"Department of Surgery University of Melbourne, Austin Health  Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nirupa","family":"Sachithanandan","sequence":"additional","affiliation":[{"name":"Department of Endocrinology St. Vincent's Hospital  Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Andrews","sequence":"additional","affiliation":[{"name":"Department of Anesthesia and Pain Management Royal Melbourne Hospital  Parkville Australia"},{"name":"Department of Anesthesia Perioperative and Pain Medicine Unit, The University of Melbourne  Parkville Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie A.","family":"Miller","sequence":"additional","affiliation":[{"name":"Endocrine Surgery Unit Royal Melbourne Hospital  Victoria Australia"},{"name":"Epworth Freemasons Hospital  Victoria Australia"},{"name":"University of Melbourne Department of Surgery  Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,7,15]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(80)91783-3"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-126-6-199703150-00003"},{"key":"e_1_2_5_4_1","first-page":"N57","article-title":"Asymptomatic primary hyperparathyroidism: new issues and new questions\u2013bridging the past with the future","volume":"17","author":"Bilezikian JP","year":"2002","journal-title":"J Bone Miner Res"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-003-6812-3"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198520110-00006"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(60)90134-3"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-199609000-00007"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-197708000-00004"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.1989.01410060038008"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-197603000-00010"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004230050113"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/hed.21215"},{"key":"e_1_2_5_14_1","first-page":"14","article-title":"Surgical anatomy of human parathyroid glands","volume":"95","author":"Akerstr\u00f6m G","year":"1984","journal-title":"Surgery"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-3944(00)00405-3"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/hed.23124"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1007\/s002680020067"},{"key":"e_1_2_5_18_1","first-page":"158","article-title":"Aberrant parathyroid adenoma within the vagus nerve","volume":"21","author":"Reiling RB","year":"1972","journal-title":"Lahey Clin Bull"},{"key":"e_1_2_5_19_1","first-page":"814","article-title":"The anatomy of primary hyperparathyroidism","volume":"92","author":"Thompson NW","year":"1982","journal-title":"Surgery"},{"key":"e_1_2_5_20_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.12.5.1529135"},{"key":"e_1_2_5_21_1","first-page":"304","article-title":"Ectopic parathyroid tissue within the vagus nerve.
