Study Design Case report. Objective Sotos syndrome is a rare genetic disorder which is characterized by excessive physical growth during the first few years of life. The principal features of this condition include macrocephaly, learning disability and physical overgrowth. The current diagnosis of Sotos Syndrome is based on identification of genetic mutations and deletions in the NSD family (the Nuclear-receptor-binding SET-Domain containing protein). Single suture craniosynostosis has been reported in a few cases of Sotos syndrome. We report an atypical presentation of multi-suture craniosynostosis in a child with Sotos Syndrome. Methods The initial phenotypical presentation was consistent with left coronal craniosynostosis. She underwent strip suturectomy and orthotic helmeting with failure to correct her anterior plagiocephaly and orbital dysmorphology. Additional post-operative investigations revealed a multi-suture craniosynostosis. She subsequently underwent an anterior cranial vault reconstruction and fronto-orbital advancement. Conclusions Sotos Syndrome can be associated with single or multi-suture craniosynostosis. This is likely driven by the overgrowth status of this disease. In our case report, the patient presents with unicoronal craniosynostosis which progressed to multi-suture craniosynostosis. Therefore, a multidisciplinary approach and close monitoring by craniofacial surgeons, neurosurgeons, developmental paediatricians and other allied teams is required in the care of such patients.
