Craniosynostosis in a child with I-cell disease: The need for genetic analysis before contemplating surgery in craniosynostosis

We are reporting a rare case of I-cell disease presenting with craniosynostosis. An 11-month-old child presented with abnormal head shape, developmental delay and bent bones. We planned for corrective surgery for craniosynostosis, but on genetic analysis I-cell disease was confirmed. After explaining the prognosis of I-cell disease, parents denied surgery. This case report emphasizes the fact that syndromic evaluation of craniosynostosis is very much essential before proceeding for corrective surgery.
