Resumo: 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.

Relato de caso: Uma paciente do sexo feminino buscou tratamento por conta de um edema na região da maxila, associado a dispneia noturna. O uso de tomografia computadorizada de eixo cônico revelou uma imagem hipodensa invadindo o seio maxilar direito. O valor médio do ADC foi 2,07 ± 0,30 × 10-³ mm²/s e contribuiu para a definição da hipótese de diagnóstico, diferenciando a lesão de seu principal diagnóstico diferencial. Exame histopatológico confirmou a suspeita de mixoma odontogênico. Conclusão: Mixoma odontogênico é uma rara e benigna neoplasia mesenquimal, de caráter localmente agressivo. Parâmetros de sequência de difusão e valores ADC podem ser úteis para diferenciar o mixoma odontogênico de outras lesões odontogênicas.Universidade de São Paulo.
