Abstract
Glycogen storage disease type II (GSDII), also referred to as Pompe disease or acid maltase deficiency, is a rare inherited condition caused by a deficiency in acid alpha-glucosidase (GAA) enzyme activity (Tinkle and Leslie. GeneReviews,
2008.
http://www.genetests.org). The condition is often classified by age of presentation, with infantile and late onset variants (Laforet et al. J Neurology 55:1122–8,
2000). Late onset tends to present with progressive proximal muscle weakness and respiratory insufficiency (Winkel et al. J Neurology 252:875–84,
2005). We report two cases of biopsy confirmed adult onset GSDII, along with key Magnetic Resonance (MR) images.
