Ultrasound (US) evaluation revealed a lesion that was diagnosed as a thyroid nodule. After a nondiagnostic FNA, she developed a large neck hematoma and her PHPT went into remission. Soon thereafter, her hyperparathyroidism recurred, and she underwent parathyroidectomy and thyroid lobectomy, which confirmed a large parathyroid adenoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Summary:<\/jats:title>\n                    <jats:p>This report illustrates that remission of PHPT can occur because of FNA-induced hemorrhage leading to autoinfarction of a parathyroid adenoma. Following autoinfarction, the patient's parathyroid hormone and calcium levels must be monitored closely as the remission of PHPT may be temporary. Further, although US is a fast, inexpensive, often reliable modality for diagnosing neck masses, it does not always accurately identify parathyroid adenomas.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Clinicians must be cognizant of the possibility that parathyroid adenomas can masquerade as thyroid nodules on US, especially as most patients with parathyroid adenomas are asymptomatic at presentation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/thy.2010.0200","type":"journal-article","created":{"date-parts":[[2011,5,26]],"date-time":"2011-05-26T20:37:38Z","timestamp":1306442258000},"page":"805-808","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Fine-Needle Thyroid Aspiration\u2013Induced Hemorrhage of an Unsuspected Parathyroid Adenoma Misdiagnosed as a Thyroid Nodule: Remission and Relapse of Hyperparathyroidism"],"prefix":"10.1177","volume":"21","author":[{"given":"Jessica H.","family":"Maxwell","sequence":"first","affiliation":[{"name":"University of Pittsburgh Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louise","family":"Giroux","sequence":"additional","affiliation":[{"name":"University of Pittsburgh Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"Bunner","sequence":"additional","affiliation":[{"name":"Wheeling Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Umamaheswar","family":"Duvvuri","sequence":"additional","affiliation":[{"name":"University of Pittsburgh Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,7,1]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(09)60507-9"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.surg.2008.09.006"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1089\/thy.2008.0263"},{"key":"e_1_3_2_5_2","first-page":"1040","article-title":"Vascular proliferation of the thyroid.
