We report a case of a 31\u2010year\u2010old woman with primary hyperparathyroidism (PHPT) due to a giant PC, which presented with biochemical features of hyperparathyroidism, compressive symptoms in the neck structures, and a unique ultrasonographic \u201csnowstorm\u201d pattern, mimicking thyroid pathology. Diagnosis was confirmed postoperatively by histopathology. This case highlights the importance of including PCs in the differential diagnosis of cystic neck masses, particularly when biochemical and imaging findings are discordant.<\/jats:p>","DOI":"10.1155\/crie\/9811283","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T14:50:29Z","timestamp":1764773429000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Giant Functional Parathyroid Cyst With \u201cSnowstorm\u201d Phenomenon: A Rare Clinical and Imaging Presentation"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9197-4051","authenticated-orcid":false,"given":"Ismet R.","family":"Bajrami","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9541-7683","authenticated-orcid":false,"given":"Brunilda I.","family":"Haxhiu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4934-2410","authenticated-orcid":false,"given":"Luljeta Z.","family":"Abdullahu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2496-4387","authenticated-orcid":false,"given":"Nimet H.","family":"Orqusha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Basri Z.","family":"Lenjani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilir N.","family":"Kurtishi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vjollca I.
