Radicular cyst involving maxillary sinus: A report of rare case

A pathological cavity lined by epithelium containing either fluid or semifluid substance is termed as cyst. The cyst associated with the teeth is called as odontogenic cyst. The periapical cyst or Radicular cyst is one among the odontogenic cysts which is most prevalent and associated with a dead or non-vital tooth. The epicentre of these cysts is mostly the apices of the involved non-vital teeth, however they may also be found on the lateral aspects of the roots in relation to lateral accessory root canals. They are inflammatory in nature. Most of the radicular cysts are small in size, but sometimes it can extend to displace maxillary sinus. In this situation, careful examination with the use of computed tomography (CT) helps you to distinguish the pathology arising from maxillary sinus itself or is it odontogenic origin causing displacement of the sinus. This article is highlighting the importance of advanced diagnostic aids like computed tomography in managing a rare case of massive radicular cyst involving the maxillary sinus in 52 year female which was treated surgically.
