We present a case of an ectopic parathyroid adenoma at the level of the pyriform sinus. A 41\u2010year\u2010old female was evaluated for primary hyperparathyroidism. Following non\u2010localizing ultrasound and planar sestamibi imaging, the patient underwent SPECT\/CT and 4\u2010D computed tomography demonstrating evidence of an ectopic parathyroid adenoma. The surgical approach was modified based on the location. Following extirpation, PTH fell from 80 to 16 pg\/mL, and the 15\u2010min post\u2010excision level remained stable at 14pg\/mL, indicating a biochemical cure. While rare, undescended parathyroid adenoma should be considered when preoperative imaging fails to identify a target adenoma or after unsuccessful surgery. The combined use of 99m Tc\u2010MBI or 4D CT and other anatomical scans may improve diagnostic accuracy. Due to the potential need to perform a second incision to conduct a four\u2010gland exploration, preoperative patient discussion regarding surgical risks may differ from that of a standard parathyroidectomy.<\/jats:p>","DOI":"10.1002\/ccr3.7987","type":"journal-article","created":{"date-parts":[[2023,10,11]],"date-time":"2023-10-11T01:02:55Z","timestamp":1696986175000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Undescended superior parathyroid: A case report"],"prefix":"10.1002","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-8473-8965","authenticated-orcid":false,"given":"Elliott M.","family":"Sina","sequence":"first","affiliation":[{"name":"Sidney Kimmel Medical College Thomas Jefferson University  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chihun J.","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Thomas Jefferson University Hospital  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth E.","family":"Cottrill","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2014Head and Neck Surgery Thomas Jefferson University Hospital  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,10,10]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01658522"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2005.10.049"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/MNM.0000000000000262"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MNM.0b013e32834557a3"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.3389\/fendo.2021.760419"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00259-021-05334-y"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.10.4459"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2015142393"}],"container-title":["Clinical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccr3.7987","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,11,27]],"date-time":"2025-11-27T14:21:29Z","timestamp":1764253289000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccr3.7987"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,10]]},"references-count":8,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2023,10]]}},"alternative-id":["10.1002\/ccr3.7987"],"URL":"https:\/\/doi.org\/10.1002\/ccr3.7987","archive":["Portico"],"relation":{},"ISSN":["2050-0904","2050-0904"],"issn-type":[{"value":"2050-0904","type":"print"},{"value":"2050-0904","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,10]]},"assertion":[{"value":"2023-07-31","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-09-19","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-10-10","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e7987"}}
