A 22-Year-Old Woman With Hypertension and Hypokalemia Due to a Juxtaglomerular Cell Tumor

Abstract

Secondary hypertension is responsible for less than 10% of cases of hypertension. If associated with hypokalemia, it may be due to primary or secondary hyperaldostronism, the latter being rarely caused by renin-secreting tumors. We present a 22-year-old woman with a history of hypertension and repeated hypokalemia, who was finally diagnosed with a small renin-secreting tumor after extensive paraclinical workup and imaging studies.
