Rhabdomyolysis: a rare complication of Hashimoto's thyroiditis precipitated by statin therapy.

Hashimoto's thyroiditis (HT) or chronic lymphocytic thyroiditis is the most common form of primary hypothyroidism. Muscular manifestations like weakness, pain, stiffness and elevated muscle enzymes have been noticed in hypothyroidism. Statins are also known to cause myositis and rhabdomyolysis. This is a case of a middle-aged man, on statin therapy, who presented with severe muscle aches and pain and was found to have rhabdomyolysis. Further evaluation revealed an underlying HT as the culprit for his condition. He was managed with intravenous fluids and levothyroxine along with cessation of statins, following which he improved. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.
