Reninom – en ovanlig men botbar orsak till sekundär hypertoni

• Reninoma - rare juxtaglomerular tumor associated with hypertension We present a case study of two female patients, aged 20-30 years, who were diagnosed with reninoma, a rare juxtaglomerular tumor associated with hypertension, high plasma renin and hypokalemia. Both patients were referred to the Department of Internal Medicine at Sahlgrenska University Hospital, but their cases were ten years apart. In both instances, the renin-secreting tumor was surgically removed, resulting in the normalization of blood pressure without the need for antihypertensive medication. Based on our findings, we recommend physicians interested in hypertension to analyze plasma renin levels before starting antihypertensive treatment in young patients. Additionally, we suggest performing an MRI of the kidneys followed by renal vein catheterization, which can confirm but not exclude the presence of a reninoma. It is important to note that treatment with RAAS (renin-angiotensin-aldosterone system) blockers may mask the effects of reninoma on blood pressure and potassium levels. Since RAAS blockers are contraindicated during pregnancy, it is of particular importance to diagnose reninoma in young women of childbearing age.
