Here, we present an interesting case with elevated catecholamines, thyroid nodules, and hypercalcitoninemia. A 46-year-old woman with complaint of abdominal pain was recently hospitalized. Abdominal computed tomography elicited a 7\u00a0cm left adrenal mass. Upon presentation to our clinic, the patient complained of abdominal pain, nausea, and diaphoresis. Laboratory studies showed elevated catecholamines, and a pheochromocytoma was subsequently diagnosed. Further evaluation elicited elevated calcitonin levels and a suspicious 3\u00a0cm left thyroid nodule, inciting concern for medullary thyroid carcinoma. The patient underwent an uneventful robot-assisted laparoscopic left adrenalectomy. Surgical pathology confirmed a pheochromocytoma. Post-operative calcitonin levels resolved to within normal range. The patient elected to undergo a left hemithyroidectomy. Surgical pathology confirmed calcitonin-negative nodular hyperplasia, negative for malignancy. The patient\u2019s diagnosis was confined to a pheochromocytoma. Clinicians should investigate high calcitonin levels associated with a pheochromocytoma as it may not always be ascribed to the thyroid.<\/jats:p>","DOI":"10.1177\/00031348221117035","type":"journal-article","created":{"date-parts":[[2022,7,21]],"date-time":"2022-07-21T07:31:05Z","timestamp":1658388665000},"page":"6227-6229","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Elevated Calcitonin Levels in a Patient With a Pheochromocytoma: A Case Report"],"prefix":"10.1177","volume":"89","author":[{"given":"Areej","family":"Shihabi","sequence":"first","affiliation":[{"name":"Division of Endocrine and Oncologic Surgery, Department of Surgery, School of Medicine, Tulane University, New Orleans, LA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter P.","family":"Issa","sequence":"additional","affiliation":[{"name":"School of Medicine, Louisiana State University, New Orleans, LA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine","family":"Cironi","sequence":"additional","affiliation":[{"name":"Division of Endocrine and Oncologic Surgery, Department of Surgery, School of Medicine, Tulane University, New Orleans, LA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmoud","family":"Omar","sequence":"additional","affiliation":[{"name":"Division of Endocrine and Oncologic Surgery, Department of Surgery, School of Medicine, Tulane University, New Orleans, LA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed","family":"Abdelgawad","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Texas Health Science Center, UT Health East Texas, Tyler, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emad","family":"Kandil","sequence":"additional","affiliation":[{"name":"Division of Endocrine and Oncologic Surgery, Department of Surgery, School of Medicine, Tulane University, New Orleans, LA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2022,7,21]]},"reference":[{"key":"bibr1-00031348221117035","doi-asserted-by":"publisher","DOI":"10.1097\/CRD.0000000000000141"},{"key":"bibr2-00031348221117035","doi-asserted-by":"publisher","DOI":"10.1016\/j.maturitas.2013.12.009"},{"key":"bibr3-00031348221117035","doi-asserted-by":"publisher","DOI":"10.1590\/S1807-59322009000700015"},{"key":"bibr4-00031348221117035","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.06.0827"}],"container-title":["The American Surgeon\u2122"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348221117035","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/00031348221117035","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/00031348221117035","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T12:37:43Z","timestamp":1777379863000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/00031348221117035"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,7,21]]},"references-count":4,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2023,12]]}},"alternative-id":["10.1177\/00031348221117035"],"URL":"https:\/\/doi.org\/10.1177\/00031348221117035","relation":{},"ISSN":["0003-1348","1555-9823"],"issn-type":[{"value":"0003-1348","type":"print"},{"value":"1555-9823","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,7,21]]}}}
