Fibrous Dysplasia in Craniosynostosis

Area of Science:

• Pediatric craniofacial surgery
• Medical genetics
• Developmental biology

Background:

• Craniosynostosis is a congenital condition involving premature fusion of skull sutures.
• Fibrous dysplasia is a rare bone disorder where normal bone is replaced by fibrous tissue.
• The co-occurrence of these conditions is infrequently reported.

Purpose of the Study:

• To report on two pediatric cases of craniosynostosis with subsequent development of fibrous dysplasia.
• To detail the clinical presentation, management strategies, and patient outcomes.
• To explore a potential, previously unrecognized association between craniosynostosis and fibrous dysplasia.

Main Methods:

• Retrospective chart review at a specialized craniofacial center.
• Analysis of medical histories, clinical examinations, and diagnostic imaging.
• Longitudinal follow-up data assessment for cranial morphology and neurological status.

Main Results:

• Two pediatric patients (one male, one female) were identified with craniosynostosis and fibrous dysplasia.
• The male patient had sagittal synostosis treated with cranial vault remodeling; the female patient with metopic synostosis was managed non-surgically.
• Both patients showed stable cranial morphology and no neurological compromise during follow-up.

Conclusions:

• The presented cases suggest a possible, previously undocumented association between craniosynostosis and fibrous dysplasia.
• While the association may be coincidental, further investigation is warranted.
• Understanding this potential link could inform future diagnostic and management approaches.
