We report a case of a 14-year-old girl referred to our oncology centre due to an abdominal mass. She had an 11-month history of paroxysmal episodes of headache, nausea, dizziness, palpitations and visual disturbances. Imaging studies showed a left paravertebral mass measuring 5.8\u00d74.6\u00d73.5\u2005cm. Metaiodobenzylguanidine scintigraphy revealed an abnormal hyperfixation on the left upper quadrant. Chromogranin A was elevated, as well as normetanephrine. The patient was submitted to surgery during which a connection between this mass and the adrenal gland was found. A diagnosis of pheochromocytoma was performed.<\/jats:p>","DOI":"10.1136\/bcr-2015-211393","type":"journal-article","created":{"date-parts":[[2015,8,5]],"date-time":"2015-08-05T08:57:24Z","timestamp":1438765044000},"page":"bcr2015211393","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Much more than anxiety\u2026"],"prefix":"10.1136","volume":"2015","author":[{"given":"Joana","family":"Teixeira","sequence":"first","affiliation":[{"name":"Paediatrics Department, Hospital de Braga, Braga, Portugal"}]},{"given":"Marta","family":"Almeida","sequence":"additional","affiliation":[{"name":"Paediatrics Department, Instituto Portugu\u00eas de Oncologia do Porto, Oporto, Portugal"}]},{"given":"Mariana","family":"Afonso","sequence":"additional","affiliation":[{"name":"Paediatrics Department, Instituto Portugu\u00eas de Oncologia do Porto, Oporto, Portugal"}]},{"given":"Armando","family":"Pinto","sequence":"additional","affiliation":[{"name":"Paediatrics Department, Instituto Portugu\u00eas de Oncologia do Porto, Oporto, Portugal"}]}],"member":"239","published-online":{"date-parts":[[2015,8,5]]},"reference":[{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2009-2830"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.2","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2005-2299"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.3","doi-asserted-by":"crossref","first-page":"107","DOI":"10.1159\/000074660","article-title":"Diagnostic imaging of pheochromocytoma","volume":"31","author":"Pacak","year":"2004","journal-title":"Front Horm Res"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.4","doi-asserted-by":"publisher","DOI":"10.2350\/09-04-0635-CP.1"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.5","doi-asserted-by":"publisher","DOI":"10.1097\/MED.0b013e32835fcc45"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3468(03)00208-2"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.7","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2013-0492"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.8","first-page":"502734","article-title":"SDHB-associated paraganglioma in a pediatric patient and literature review on hereditary pheochromocytoma-paraganglioma syndromes","volume":"2014","author":"Choat","year":"2014","journal-title":"Case Rep Endocrinol"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.9","doi-asserted-by":"publisher","DOI":"10.1634\/theoncologist.2011-0120"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.10","doi-asserted-by":"publisher","DOI":"10.1080\/08880010490515029"},{"key":"2025082701243969000_2015.aug05_1.bcr2015211393.11","unstructured":"McNicol AM , Young WF , Kawashima A , et al .
