Craniosynostosis in two African green monkeys

Area of Science:

• Veterinary Pathology
• Developmental Biology
• Primate Medicine

Background:

• Craniosynostosis is a congenital condition characterized by the premature fusion of cranial sutures.
• While common in human infants, severe forms are rare in non-human primates.
• Understanding the etiology and presentation in animal models is crucial for comparative pathology.

Observation:

• Two infant African green monkeys presented with multiple craniosynostoses.
• Cranial bones were overlapped and fused across all sutures.
• Evidence of pressure necrosis in the cerebral cortices was observed due to restricted skull growth.

Findings:

• The observed craniosynostosis in these primates exhibited an overlapping bone pattern distinct from human presentations.
• The condition led to significant intracranial pressure and subsequent cerebral damage.
• Potential causes include teratogen exposure or genetic factors, supported by the infants' close birth dates and shared father.

Implications:

• This case highlights a unique manifestation of craniosynostosis in African green monkeys, expanding knowledge of primate developmental disorders.
• The findings suggest a need for further research into the genetic and environmental factors influencing craniosynostosis in non-human primates.
• Comparative studies of this condition can offer insights into human craniosynostosis and its management.
