INTRODUCTION: Tonsillolith is a rare type of dystrophic calcification in the palatine tonsils or in the peritonsilar region, which can mimics several intraosseous radiopaque lesions when evaluated by two-dimensional or overlapping images. This may lead to an erroneous diagnosis and to invasive and unnecessary procedures. This study reports a case of tonsillolith that was wrongly diagnosed as an odontoma. CASE REPORT: A patient with primary diagnosis of odontoma in the mandibular ramus was referred to surgical treatment of this lesion. CONCLUSION: Computed tomography (CT) scans are fundamentally important to establish differential diagnosis and appropriate treatment for the patient.
