This is a case report of an odontogenic keratocyst of the maxilla initially diagnosed and treated as a periodontal abscess. The occurrence of odontogenic keratocyst in the maxilla with involvement of the antrum is relatively rare. The radiological appearance of this lesion on both conventional and panoramic radiography can be misinterpreted and emphasizes the usefulness of the computed tomography in this region.

D009807	Odontogenic Cysts	Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinized (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation.	Keratocysts,Cyst, Odontogenic,Cysts, Odontogenic,Keratocyst,Odontogenic Cyst
