The Calcifying Cystic Odontogenic Tumor(CCOT) is an uncommon lesion that demonstrates considerable histopathologic diversity and variable clinical behavior. A CCOT is rarely found in everyday practice. According to Kramer and Pindborg as well as majority of other authors’ classification, since 1992 the World Health Organization favored the use of the term calcifying cystic odontogenic tumor, described it as a cystic or neoplastic-like odontogenic pathological lesion of the jaw, and classified it as a benign odontogenic tumor. Ultrasonography(USG) is an inexpensive, non-invasive, and almost an available technique that is well tolerated by patient. In recent years many investigations focused on the use of ultrasonography in maxillofacial region as well as in intra osseous lesions of the jaws. This paper describes a 34 year old female with a painless mild swelling in the left anterior maxillary region associated with an impacted lateral incisor. The Panoramic, lateral occlusal and periapical view findings showed well-defined corticated unilocular mixed lesion with cluster of small pebbles calcifications. USG examination, using linear probe transducer, and also evaluation of location, size, internal echoe and boundary of the tumor were performed and documented. The main USG features of the tumor appeared as anechoic pattern cystic like lesion with some calcifying contents. Pathologic diagnosis was obtained by examining the surgical specimen. Therefore, ultrasonography may be used as an effective supplementary diagnostic tool for maxillofacial lesions.
