Mixed sclerosing bone dysplasia

Dr Craig Hacking et al.

Mixed sclerosing bone dysplasia (MSBD) is a combined and highly variable bone sclerosing spectrum with shared features of 3 radiological entities:

Some authors propose these 3 conditions are within the same sclerosing spectrum 5. Little is known about this overlap dysplasia, which is proposed to be due to abnormal endochondral and intramembranous ossification. It may share an underlying etiology and loss of function mutations in the LEMD3 gene has been proposed 6.

It has features of all 3 components but is highly variable and its etiology may be inherited or sporadic.
