Late-Onset Lipid Storage Myopathy with Fatal Hepatosteatosis

Abstract

Hepatosteatosis, a common condition, is increasing in prevalence. It is typically associated with diet, alcohol consumption and obesity. In some cases, a rare genetic disease may be the underlying defect. Lipid storage myopathy (LSM) is a genetic disease caused by lipid metabolism defects. LSM often affects the muscles, heart and liver. Coenzyme Q, riboflavin or carnitine replacement can be beneficial in some cases. We describe a patient who presented with liver failure and was unresponsive to treatment.
