The cementoma is a common disease of the dental root apex, which generally occurs in the maxilla and the mandible, but the cementoma occurring in the long bone is rare. Moreover, the incidence of cementoma in the calcaneus is extremely infrequent.
The present study reports an unusual case of a 19-year-old girl, who complained of pain in the left heel. Subsequent radiographs and computed tomography (CT) were used in the diagnosis. The imaging features of the lesion included a radiopaque matrix and radiolucent tissue, particularly an arc-shaped fat band. An excisional biopsy was performed. Histopathological examination confirmed the diagnosis of cementoma in the calcaneus. After the operation, the patient was followed up without recurrence.
Imaging examination plays an important role in the differential diagnosis of cementoma of the calcaneus.
牙骨质瘤是一种常见的牙根尖疾病，通常发生在上颌骨和下颌骨，但发生在长骨的牙骨质瘤很少见。此外，跟骨牙骨质瘤的发病率极低。
本研究报告了一例不寻常的病例，一名19岁女孩，主诉左脚后跟疼痛。随后通过X线片和计算机断层扫描（CT）进行诊断。病变的影像学特征包括不透射线的基质和透光组织，特别是一条弧形脂肪带。进行了切除活检。组织病理学检查证实为跟骨牙骨质瘤。术后对患者进行随访，无复发。
影像学检查在跟骨牙骨质瘤的鉴别诊断中起重要作用。
