Open full text 9 citations

Abstract

BACKGROUND: Severe hypokalemia is known to cause muscle paralysis, and renal tubular acidosis is a recognized cause. Cystic disease of the kidney is associated with severe hypokalemia. CASE PRESENTATION: We report a 33-year-old male patient who presented with generalized limb weakness caused by severe hypokalemia due to renal tubular acidosis, who was found to have renal medullary cysts. CONCLUSION: The association of cystic renal disease with hypokalemia, and the possible pathophysiological basis of the development of renal cysts in patients with severe hypokalemia, are discussed.
