Roentgenographic diagnosis of mucopolysaccharidosis with particular reference to Morquio syndrome

Mucopolysaccharidosis (MPS) comprises a group of conditions associated with an abnormality in glycoprotein or mucopolysaccharides metabolism. Types of MPS identified are MPS I-H (Hurler’s syndrome, gargoylism), MPS II (Hunter’s syndrome), MPS III (Sanfilippo’s syndrome), MPS IV (Morquio-Brailsford syndrome), MPS I-S (Scheie’s syndrome) and MPS VI (Maroteaux- Lamy syndrome). The Hunter type is inherited as an X-linked recessive; the others are autosomal recessive. Patients with MPS IV can usually be clinically distinguished from patients with other forms of MPS; their intelligence is unimpaired, in contrast with other forms of MPS. Husler coined the term dysostosis multiplex to describe the skeletal findings. SA JOURNAL OF RADIOLOGY February 2012
