Preoperative CT scan and MRI demonstrated the ectopic location of the parathyroid adenoma. The patient underwent successful parathyroidectomy with cure of his hyperparathyroidism. On pathologic exam, the specimen was made up of a parathyroid adenoma and adjacent thymic tissue, indicating that it was likely an undescended lower parathyroid gland arising from the third pharyngeal pouch. Ectopic retropharyngeal parathyroid adenomas are very rare and to our knowledge, none have been previously described in adolescents.<\/jats:p>","DOI":"10.1093\/omcr\/omz129","type":"journal-article","created":{"date-parts":[[2019,12,31]],"date-time":"2019-12-31T03:27:56Z","timestamp":1577762876000},"page":"519-523","source":"Crossref","is-referenced-by-count":5,"title":["Undescended retropharyngeal parathyroid adenoma with adjacent thymic tissue in a 13-year-old boy with primary hyperparathyroidism"],"prefix":"10.1093","volume":"2019","author":[{"given":"Anthony M","family":"Kordahi","sequence":"first","affiliation":[{"name":"Department of Surgery, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ron S","family":"Newfield","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Pediatric Endocrinology, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen W","family":"Bickler","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"},{"name":"Department of Pediatrics, Division of Pediatric Endocrinology, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun Q","family":"Mo","sequence":"additional","affiliation":[{"name":"Department of Pathology, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paritosh C","family":"Khanna","sequence":"additional","affiliation":[{"name":"Department of Pediatric Radiology, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julie","family":"Bykowski","sequence":"additional","affiliation":[{"name":"Department of Radiology, University of California San Diego, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0086-2159","authenticated-orcid":false,"given":"Michael","family":"Bouvet","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of California San Diego and Rady Children\u2019s Hospital, San Diego, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,12,31]]},"reference":[{"key":"2019123103275056500_ref1","first-page":"180","article-title":"Working group on calcium M. primary hyperparathyroidism in neonates and childhood.
