Its etiology remains unknown. Limitations on mouth opening and also tension in the region of the hypertrophied muscle are symptoms reported. This paper reports a case of masseter muscle hypertrophy diagnosed using imaging modalities such as conventional radiography, computed tomography and magnetic resonance imaging scans. The familiarity with this condition is important to settle the differential diagnosis with other pathologies such as parotid gland tumors and dental infection.347-350engComputed tomography scanHypertrophyMagnetic resonance imagingMasseter muscleRadiologyMasseter muscle hypertrophy - case reportArtigo10.1590/S0103-64402006000400015S0103-64402006000400015Acesso aberto2-s2.0-340471736482-s2.0-34047173648.pdf1067437159861527
