Radiograph showed an ectopic tooth along with large cystic lesion occupying the entire maxillary sinus and resorption of the root of retained deciduous second molar [Figure 1]. The cystic lesion was attached to the tooth cemento-enamel junction (CEJ) [Figure 1d].

Computed tomography (CT) scan showed a well defined irregular opacity surrounded by a soft tissue mass in the right maxillary sinus [Figure 2]. The tooth along with surrounding soft tissue that was attached to the CEJ was removed through a Caldwell-Luc procedure [Figure 2c].

Scan examination, the axial and coronal views revealed fracture of right antero-lateral wall of the maxillary sinus along with ectopic maxillary third molar within the sinus [Figure 6]. Surgical removal of the tooth along with associated soft tissue and the bony fragments was carried out under general anesthesia.
