Description

A 58-year-old man with recurrent attacks of cerebrovascular accidents associated with polycythemia vera and hyperkalemia with a sodium losing tendency during dietary sodium restriction is described. The endocrinological studies revealed that the hyperkalemia primarily resulted from the selective deficiency of aldosterone associated with hyporeninemia. The failure to correct the hyporeninemic hypoaldosteronism despite the definite improvements in the hematological findings during busulfan therapy seems to suggest a coincidental occurrence of polycythemia vera and hyporeninemic hypoaldosteronism.
