case_images: There was considerable elevation of the alar base and obliteration of the right nasal cavity [Figure 1].

case_images: T-high-field magnetic resonance imaging (MRI) revealed a soft-tissue mass in the central aspect of the right maxilla extending into nasal cavity with cranial displacement of the deciduous central incisor [Figure 2a]. The child was subsequently taken up for excision of the nasomaxillary mass under general anesthesia [Figure 2b and c].
