Odontogenic myxoma (OM) is an infiltrative benign bone tumor that occurs almost exclusively in the facial skeleton. The radiographic characteristics of odontogenic myxoma may produce several patterns, making diagnosis difficult. Cone-beam computed tomography (CBCT) may prove extremely useful in clarifying the intraosseous extent of the tumor and its effects on surrounding structures. Here, we report a case of odontogenic myxoma of the mandible in a 27-year-old female. The patient exhibited a slight swelling in the left mandible. Surgical resection was performed. No recurrence was noted. In the CBCT sections, we observed perforation of the cortical plate and radiopaque line that extended from the periosteum, resembling "sunray" appearance-a rare feature of OM-which could not be assessed by panoramic radiography.
牙源性黏液瘤（OM）是一种几乎仅发生于面颅骨的浸润性良性骨肿瘤。牙源性黏液瘤的影像学特征可能呈现多种表现形式，这使得诊断颇具难度。锥形束计算机断层扫描（CBCT）在明确肿瘤的骨内范围及其对周围结构的影响方面可能极为有用。在此，我们报告一例27岁女性下颌骨牙源性黏液瘤病例。该患者左侧下颌骨出现轻微肿胀。实施了手术切除。未观察到复发情况。在CBCT图像上，我们观察到皮质骨板穿孔以及从骨膜延伸出的不透射线的线条，类似“日光”外观——这是牙源性黏液瘤的一种罕见特征——全景X线片无法评估此特征。
