Hepatic Steatosis: A Presentation of Cholesteryl Ester Storage Disease.

Cholesteryl ester storage disease is a rare genetic disorder caused by mutations in the LIPA gene, resulting in lysosomal acid lipase deficiency, which leads to abnormal accumulation of cholesteryl esters and triglycerides within lysosomes. We describe a case of late-onset cholesteryl ester storage disease in a woman with elevated liver enzymes, histologic evidence of microvesicular steatosis and cirrhosis, with a confirmed LIPA mutation, who initiated enzyme replacement therapy with sebelipase alfa. This case highlights the importance of considering hereditary disorders of lipid metabolism in patients presenting unexpectedly with steatotic liver disease in the absence of significant metabolic risk factors.
