A 14-year-old girl developed a firm mass at the base of the tongue. Computed tomography indicated marked density suggesting either a foreign body or bony tissue. A thyroid scan confirmed the presence of a normally sized and positioned gland. The mass was removed in toto and found to be an osteoma. This is the first report of a case in which the diagnosis of this rare developmental lesion of the tongue was achieved preoperatively based on clinical and radiologic information. This experience should lead to greater awareness of this entity in the future. Recognition of this entity in the pediatric age group is especially useful in avoiding misdiagnosis of other, potentially more aggressive types of tongue mass lesions. Our case demonstrates that it is possible to detect this entity using computed tomography. The dense calcification is truly characteristic of the tumor and may be relied upon to exclude alternative soft tissue mass lesions. While other forms of osseous and cartilagenous neoplasms, such as extraskeletal osteosarcoma and chondrosarcoma, have been reported arising in the tongue, their malignant nature should otherwise be readily apparent. Osteoma of the tongue is the favored diagnosis when mature bone tissue is imaged at the base of the tongue.
一名14岁女孩在舌根处出现一个质地坚硬的肿块。计算机断层扫描显示密度明显增高，提示可能为异物或骨组织。甲状腺扫描证实甲状腺大小和位置正常。肿块被完整切除，发现是一个骨瘤。这是首例基于临床和放射学信息在术前确诊这种罕见的舌部发育性病变的病例报告。这一经验应能使未来对该疾病有更高的认识。在儿童年龄组中识别该疾病对于避免误诊其他可能更具侵袭性的舌部肿块病变尤为有用。我们的病例表明，使用计算机断层扫描可以检测到这种疾病。致密的钙化是该肿瘤的真正特征，可据此排除其他软组织肿块病变。虽然已有报道称舌部会出现其他形式的骨和软骨肿瘤，如骨外骨肉瘤和软骨肉瘤，但它们的恶性性质通常应很明显。当在舌根处成像显示成熟骨组织时，舌骨瘤是首选诊断。
