Focal neurologic signs associated with hyperkalemia.
A patient with end-stage renal disease had a flaccid hemiparesis in conjunction with severe hyperkalemia. The hemiparesis resolved with treatment of the hyperkalemia. The patient was later found to have extracranial vascular disease, and we propose that a severe metabolic abnormality associated with an area of relative cerebral ischemia caused the reversible neurologic deficit.
