Leri-Weill Dyschondrosteosis Syndrome: Analysis via 3DCT Scan

Background: Leri-Weill dyschondrosteosis (LWD) is a pseudoautosomal form of skeletal dysplasia, characterized by abnormal craniofacial phenotype, short stature, and mesomelia of the upper and lower limbs. Methods: We describe two female patients with LWD. Their prime clinical complaints were severe bouts of migraine and antalgic gait. Results: Interestingly, via a 3D reconstruction CT scan we encountered several major anomalies. Notable features of craniosynostosis through premature fusion of the squamosal sutures and partial closure of the coronal sutures were the reason behind the development of abnormal craniofacial contour. A 3D reconstruction CT scan showed apparent bulging of the clavarium through the partially synostosed coronal and totally synostosed squamosal sutures. Additional deformities include deficient number of ribs (10 ribs on both sides), defective ossification of the ischium and dysplasia of the iliac-ischial junction, and coxa valga have been noted. Conclusions: The constellation of observed deformities can be considered as a novel features associated with LWD.
