| Abstract: | We report two siblings aged 11 and 7 years, respectively, who presented with the clinical and radiographic features of opsismodysplasia
(non-lethal type). 3D computed tomography scans of the craniocervical region revealed a split atlas and os odontoideum in
both siblings. To the best of our knowledge, this is the first clinical report detailing craniocervical malformations in two
siblings with opsismodysplasia. |
