Hypokalemia in a Young Patient as Onset Sign of Reninoma, still a Complex Diagnosis

Abstract

Hypokalaemia is rare in young people without chronic disease and chronic treatment. Rarely it may be associated to secondary hypertension.

We here report a rare case of reninoma with early onset characterized by hypokalemia and chronic kidney dysfunction.

GB a 29 yy black old man was admitted in internal medicine with unexplained hypokalemia associated to onset of severe hypertension and anamnestic kidney dysfunction. During the differential diagnosis evaluation, the presence of a right reninoma was found. Therapeutic management was very difficult because the rare evidence of reninoma and the available options in this clinical setting are not clear.

The complexity clinical management and therapeutic options of similar cases are limitated by the current guidelines and to choose a long term treatment is very difficult.
