Importance of cone beam computed tomography for diagnosis of calcifying cystic odontogenic tumour associated to odontoma - Report of a case

Abstract

The calcifying cystic odontogenic tumour (CCOT) is a rare benign cystic neoplasm not infrequently associated with odontoma. This report documents a case of CCOT associated with compound odontoma arising in the anterior maxilla in a 25-year-old woman. Conventional radiographs showed a large calcified mass with poorly visualized radiolucent margins. The extent and condition of the internal structure of the CCOT associated with odontoma was able to be determined based on radiographic findings from cone beam computed tomography. This advanced image technique proved to be extremely useful in the radiographic assessment of this particular neoplasm of the jawbones.

Kyste odontogène calcifié : à propos d’un cas clinique

“…Le KOC central apparaît comme une tuméfaction asymptomatique associée à une lyse osseuse adjacente, alors que, dans sa variante périphérique, il se présente comme une formation sessile bien circonscrite non spécifique, ou une masse pédiculée, avec une surface lisse [2,3]. Le KOC est généralement asymptomatique [5,6], mais si la localisation est maxillaire, les patients peuvent parfois se plaindre d'obstructions nasales, d'épistaxis et de maux de tête [7]. Le KOC est une tumeur à évolution lente et progressive, et donc l'aspect radiologique est différent en fonction du stade d'évolution [7,8].…”

A Large Calcifying Cystic Odontogenic Tumor Occupying the Maxillary Sinus: A Case Report and Review of Literature

“…Odontogenic tumors of the jaw-bones show a wide range of radiographic manifestations that result from the presence of dental components of ectodermal and mesodermal originthe jaw-bones [10]. Specifically, as CCOT is a mixed lesion, it has a wide range of radiologic appearances.…”

Complex odontoma: A clinical case report

“…Complementary to conventional radiography, computed tomography shows more details of the internal structure which cannot be clearly seen on conventional radiography, with the ability to view a tridimensional image, being of great importance in the diagnosis and surgical planning. [23,24] In this case, the observation of the injury was through a radiographic finding in a panoramic radiograph requested by an orthodontist. After the arrival of the patient to the specialized service, periapical radiographs, new panoramic radiography, and Fan-Beam computed tomography.…”
