Þrátt fyrir endurteknar komur á bráðamóttöku og uppvinnslu á göngudeild var undirliggjandi orsök ekki greind. Síðustu þrjú árin fyrir komu hafði háþrýstingurinn versnað og viðkomandi þróað með sér sykursýki af tegund 2. Frekari uppvinnsla leiddi í ljós 3 cm hjáhnoðuæxli utan nýrans. Eftir brottnám á æxlinu er hann án lyfjameðferðar og einkennalaus. Krómfíkla- (pheochromocytoma) og hjáhnoðuæxli (paraganglioma) eru sjaldgæf orsök háþrýstings, talin vera skýring 0,1-0,6% allra tilfella, en mikilvæg að greina vegna hættulegra fylgikvilla. We report a case of a man with a 30-year history of treatment-resistant hypertension, hydropoiesis, tachycardic spells and dysgeusia. Despite repeated visits to the emergency department and work-up in an out-patient clinic, the diagnosis was unknown. Three years prior to remittance to an endocrinologist, the hypertension worsened, and he developed diabetes type-II. Further work-up revealed a 3 cm extra-adrenal pheochromocytoma, a paraganglioma. After surgical removal of the tumor, he is without medication and symptom free. Pheochromocytoma and paraganglioma are rare causes of hypertension, estimated to explain 0.1-0.6% of all cases, but nonetheless an important diagnosis to make, due to serious side effects.51497369141-145isinfo:eu-repo/semantics/openAccessMaleHumansPheochromocytomaParagangliomaAmbulatory Care FacilitiesHypertensionAdrenal Gland Neoplasmsmetanephrinepheochromocytomaneuroendocrine tumorresistant hypertensionparagangliomametanephrineneuroendocrine tumorparagangliomapheochromocytomaresistant hypertensionGeneral MedicineSDG 3 - Good Health and Well-being/dk/atira/pure/researchoutput/researchoutputtypes/contributiontojournal/article10.17992/lbl.2023.03.735
