Abstract

Objective: This report discusses the main imaging findings observed in odontogenic myxoma (OM) with an emphasis on the importance of apparent diffusion coefficient (ADC) values for diagnosis. Case report: In the present report, a female patient sought care due to an edema in the maxilla region associated with nocturnal dyspnea. Cone beam computed tomography showed a hypodense image invading the right maxillary sinus. The mean ADC value was 2.07 ± 0.30 × 10-³ mm²/s contributed to the elucidation of the diagnostic hypotheses, differentiating the lesion from its main differential diagnoses. Histopathological examination confirmed the suspicion of an odontogenic myxoma. Conclusion: OM is a rare benign mesenchymal neoplasm of locally aggressive nature. DWI parameters and ADC values can be useful to differentiate OM from other odontogenic lesions.
