anterior vertebral body beaking
Anomalies of Foramen Magnum. Marked vertebral flattening is also a striking feature. Anterior beaking is further exacerbated in the thoracic tract by the spinal kyphosis. The disorder is caused by deficient activity of the lysosomal enzyme glycosylasparaginase, which results in body fluid and tissue accumulation of a series of glycoasparagines, i.e., glycoconjugates with an aspartylglucosamine . Hurler Syndrome (mucopolysaccharidosis type I) usually presents with vertebrae showing anterior inferior beaking, and Morquio syndrome (mucopolysaccharidosis type IV) patients more frequently show anterior central vertebral body beaking and round vertebral bodies (33,34). The first group comprises variants mimicking pathological vertebral height loss, including not-yet-ossified vertebral apophyses superiorly and inferiorly, which can lead to a vertebral shape easily over-interpreted as anterior wedge fracture, physiological beaking, or spondylolisthesis associated with shortened posterior vertebral height. As such, articles are written and edited by countless contributing members over a period of time. True ribs connect to the sternum by their own costocartilage. In Hurler syndrome (MPS 1H) beaking often occurs at the inferior aspect of the anterior vertebra, while Morquio syndrome (MPS IV) and pseudoachodroplasia are often associated with beaking of the middle portion of the anterior vertebra [ 20 ].
