【摘要】：目的通過分析總結成牙骨質(zhì)細胞瘤的臨床及影像資料特征,以期提高臨床醫(yī)生對該病的診斷及鑒別。方法回顧性總結分析14例成牙骨質(zhì)細胞瘤患者的臨床及影像資料。結果 14例成牙骨質(zhì)細胞瘤患者就診年齡11~58歲,中位年齡21.0歲,平均年齡27.6歲;男女各7例;好發(fā)于下頜骨;最常見的癥狀是頜骨腫脹和疼痛。特征性影像表現(xiàn):與病變牙根融合的類圓形包塊影,可見完整的包膜影像,與周圍骨質(zhì)分界清晰。腫瘤實質(zhì)一般為團塊狀高密度影。根據(jù)腫瘤實質(zhì)密度不同可分為均質(zhì)型和非均質(zhì)型。此外病變周緣常可見骨質(zhì)增生硬化,下頜下緣骨密質(zhì)增厚。結論成牙骨質(zhì)細胞瘤在臨床及影像表現(xiàn)上有其較明顯特征性,臨床醫(yī)生應充分認識這一病變以免誤診。
[Abstract]:Objective to summarize the clinical and imaging features of cementoblastoma. Methods the clinical and imaging data of 14 patients with cementoblastoma were retrospectively analyzed. Results the age of 14 patients with cementoblastoma was 1158 years old with a median age of 21.0 years. The average age was 27.6 years old; male and female 7 cases; predilection to mandible; the most common symptom was maxillary swelling and pain. The boundary between the tumor and the surrounding bone is clear. The tumor parenchyma is usually mass high density shadow. According to the different density of tumor substance, it can be divided into homogeneous type and heterogeneous type. Conclusion the clinical and imaging features of cementoblastoma are obvious, and clinicians should fully recognize this lesion to avoid misdiagnosis.
