Abstract：
Ameloblastic fibrodentinoma (AFD) is a rare benign odontogenic tumor that resembles an ameloblastic fibroma with dysplastic dentin. This report presents a rare case of mandibular AFD with imaging features in a young patient. Panoramic radiography and computed tomography revealed a well-defined lesion with internal septa and calcified foci, causing inferior displacement of the adjacent molars as well as buccolingual cortical thinning and expansion of the posterior mandible. The lesion was surgically removed via mass excision, and the involved tooth was extracted under general anesthesia. During the 5-year follow-up period, no evidence of recurrence was observed. Radiologic features of AFD typically reveal a moderately to well-defined mixed lesion with varying degrees of radiopacity, reflecting the extent of dentin formation. Radiologists should consider AFD in the differential diagnosis when encountering a multilocular lesion with little dense radiopacity, particularly if it is associated with delayed eruption, impaction, or absence of involved teeth, on radiographic images of young patients.
摘要：
成釉细胞纤维瘤（AFD）是一种罕见的良性牙源性肿瘤，类似于具有发育不良牙本质的成釉细胞纤维瘤。本报告介绍了一名年轻患者的下颌AFD罕见病例，具有影像学特征。全景X线摄影和计算机断层扫描显示明确的病变，内部间隔和钙化灶，导致相邻磨牙的下移位以及颊舌皮质变薄和后下颌骨扩张。病灶通过肿块切除手术切除,受累牙齿在全身麻醉下拔除。在5年的随访期间，未观察到复发的证据.AFD的放射学特征通常显示中度至明确的混合病变，具有不同程度的射线不透性。反映牙本质形成的程度。放射科医师在鉴别诊断中当遇到少有密集射线不透性的多房性病变时，应考虑AFD。特别是如果它与延迟喷发有关，撞击,或者没有受累的牙齿，年轻患者的影像学图像。
