Introduction: The evaluation of the anterior fontanelle is crucial in the physical examination of the child. It’s closure occurs by a slow ossification process, frequently between four and 24 months. The delayed closure is rare and there are few cases described in Portugal. It requires etiological study. Case Report: A previously healthy 30 months child, was brought to the Pediatrics consultation because of an open anterior fontanelle. He presented a 1.5X1.5cm normotensive fontanelle, normal neurological exam and psychomotor development, without further anomalies. The evaluation of the thyroid function and bone metabolism were normal. The skull radiography and ultrasound scan didn’t show other anomalies. Discussion/Conclusion: In an over 24 months child with an open anterior fontanelle, with normal growth and development, and after excluding pathological causes, it must be considered a normal variant, and the parents should be reinsured.

Keywords : Anterior fontanelle; closure.
