Hypothyroidism-induced rhabdomyolysis and renal failure.

Renal failure, due to rhabdomyolysis, is a rare complication of hypothyroidism. We report an elderly patient with primary hypothyroidism symptoms initially presented with inability to walk, leading to renal failure. Laboratory examinations disclosed rhabdomyolysis and primary hypothyroidism. Creatinine phosphokinase, lactate dehydrogenase, and renal function test decreased to normal values shortly after thyroid hormone replacement. This report highlights that hypothyroidism should be considered in patients presenting with renal impairment associated with rhabdomyolysis.
