Cone Beam Computed Tomography Findings in Calcifying Cystic Odontogenic Tumor Associated with Odontome: A Case Report.

Phulambrikar T, Vilas Kant S, Kode M, Magar S - J Dent (Shiraz) (2015)

Bottom Line: The calcifying cystic odontogenic tumor (CCOT) is a rare cystic odontogenic neoplasm frequently found in association with odontome.Conventional radiographs showed internal calcification within the lesion but were unable to visualize its relation with the adjacent structures and its accurate extent.In this case cone beam computed tomography (CBCT) could accurately reveal the extent and the internal structure of the lesion which aided the presumptive diagnosis of the lesion as CCOT.

ABSTRACT
The calcifying cystic odontogenic tumor (CCOT) is a rare cystic odontogenic neoplasm frequently found in association with odontome. This report documents a case of CCOT associated with an odontome arising in the anterior maxilla in a 28-year-old man. Conventional radiographs showed internal calcification within the lesion but were unable to visualize its relation with the adjacent structures and its accurate extent. In this case cone beam computed tomography (CBCT) could accurately reveal the extent and the internal structure of the lesion which aided the presumptive diagnosis of the lesion as CCOT. This advanced imaging technique proved to be extremely useful in the radiographic assessment and management of this neoplasm of the maxilla.

Figure 5: Tridimensional representation of the lesion demonstrating radiopaque foci in relation with tooth #21, 22, 23.

Mentions: Panoramic radiograph was advised (Figure 4) which demonstrated unicystic cavity extending into the left maxillary sinus, with the area of radiopacity within. CBCT scan was performed to determine the extent of lesion with Kodak CS-9300 using OnDemand software that provided a 10×5 cm field of view, with 360° rotation 90 microns voxel size. The exposure factors were 84 kVp, 20-second rotation time, and 5 mA. CBCT images revealed a large, well-defined unilocular radiolucent expansile lesion with thinned cortical outline involving the entire left side of maxilla, circumscribing the entire quadrant and reaching up to the left infraorbital ridge. Within the lesion, multiple tooth-like high-density structures were observed which depicted radiographic impression of an odontome (Figure 5).
