A Rare Case of Radicular Cyst in the Maxillary Sinus Masquerading as Mucous Retention Cyst

Abstract

Cysts are pathological cavities lined by the epithelium that contains fluid or semifluid material. The term “odontogenic cyst” refers to the cyst related to the teeth. One of the most common odontogenic cysts, the periapical cyst, also known as the radicular cyst, is linked to a dead or nonvital tooth. Most often, the apices of the affected nonvital teeth serve as the epicenter of these cysts, although they can also be discovered on the lateral aspects of the roots in connection with lateral accessory root canals. There is something provocative about them. Most radicular cysts are small, but on rare occasions, they may enlarge to the point where they press against the maxillary sinus. In this instance, you can distinguish between pathology coming from the maxillary sinus itself and pathology with an odontogenic origin that is causing the sinus to be displaced by performing a comprehensive examination in conjunction with computed tomography (CT) imaging. This article highlights the use of advanced 3D diagnostic technologies like CT that details the care of a rare case of a huge radicular cyst involving the maxillary sinus in a 50-year-old female requiring surgical intervention.
