Abstract

Odontogenic myxoma (OM) is a benign, slow-growing neoplasm of ectomesenchymal origin. The radiological features are variable including unilocular or multilocular radiolucency with a well-defined or diffuse border, making the differential diagnosis difficult. These facts pose potential challenges in reaching the correct diagnosis only with radiographic examinations. In this article, two cases of OM are presented and the varied clinical and radiological features and difficulties in differential diagnosis are discussed together with the application of computed tomography (CT) and cone beam computed tomography (CBCT).
The presented cases are a 33-year-old female patient with the complaints of migration and mobility of maxillary left premolar teeth and a 30-year-old-male patient with the complaint of a firm, non-tender, fixed mass in the mandibular right posterior region. Periapical, panoramic, and CT/CBCT images revealed the presence of multilocular hypodense lesions with or without hyperdense foci in the relevant areas, and divergence and mobility of the associated teeth were also observed. Excisional biopsy and histopathological examination exhibited the definitive diagnosis of OM.
Three-dimensional advanced imaging techniques such as CT and CBCT differ from two-dimensional periapical and panoramic radiographs in that they can demonstrate more characteristic radiographic findings and clearly display the tumour in three-dimensional accuracy and perspective. Therefore, the use of advanced imaging techniques is recommended as a useful tool in the diagnostic process of OM in order to display the borders and to help in investigation of the internal structure of the tumour.
