Odontogenic myxoma in the maxilla: A case report and characteristics on CT and MR

SummaryThe findings of a computed tomography (CT) and magnetic resonance (MR) are reported in this study for a odontogenic myxoma arising in the maxilla of a 22 years-old Brazilian woman. The CT showed an expansive formation of circular aspect located in the alveolar process of the left maxilla with slight heterogeneous distinction after iodinized contrast. Unilateral crowding with displacement of some dental elements inside the lesion was shown in the MR and CT images. The MR images showed a well-defined and smooth-walled mass lesion with low signal intensity on T1-weighted images and high-signal intensity on T2-weighted images. The treatment of choice was a surgical tumoral resection and three applications of cryotherapheutic agent for 1 min in the same surgical time with interval of 5 min between them.
