This case report demonstrates a rare finding of a pediatric patient with Morning Glory anomaly and Moyamoya Disease with a palatal meningeal hamartoma discovered as a mass within a previously repaired incomplete cleft of the alveolus. Oral meningeal hamartomas are exceedingly rare with only two palatal cases described and none within a cleft palate or alveolus. These findings prompt a review of oral hamartomas with meningeal subclassification. Further discussion describes the relationship of the proposed origins of meningeal hamartomas within the setting of cleft palate development.
