title: Two maxillary lesions containing bony/calcified shells.
abstract: Because of the close anatomical relationship between the maxillary sinus and the adjacent dental region, determining the primary site of cysts in these regions can be a diagnostic dilemma. In this article, two cases with similar radiological findings are presented. These cases had lesions involving the maxillary sinus and the adjacent alveolar process; the lesions were surrounded with egg-shaped, linear opacities. Diagnoses of a residual radicular cyst in one case and a calcified mucocoele (which is very rare) in the other case were predicted with the help of radiological findings and were confirmed surgically and histopathologically.
