GM1gangliosidosis: Clinical and radiological clue to diagnosis

Abstract

GM1gangliosidosis is a rare autosomal recessive lysosomal storage disorder caused by deficiency of enzyme β-galactosidase, resulting in progressive neural and visceral accumulation of GM1gangliosides. Coarse facial features, bilateral cherry red spots, and dysostosis multiplex are important clue to diagnose this condition. We describe a case of GM1gangliosidosis with dysostosis multiplex and characteristic magnetic resonance imaging findings.
