4例口腔颌面部非霍奇金淋巴瘤的影像学表现

Four cases of X-ray and cone beam computed tomography radiographic findings of non-Hodgkin's lymphoma involving jaws in the oral and maxillofacial region

回顾性分析病理确诊的4例口腔颌面部非霍奇金淋巴瘤的锥形束CT(CBCT)以及全景影像特征,其中3例病变发生于上颌,1例累及双侧上、下颌。所有病例的CBCT表现出骨质溶解性破坏,边界不清,但其骨质破坏范围程度各异;其中2例病例的全景片可见骨质改变影像。该肿瘤的CBCT和全景片表现均存在一般恶性肿瘤的影像特征,但颌骨改变的表现多样性有待进一步研究。

Cone beam computational tomography（CBCT） and panoramic radiographs of four oral and maxillofacial non- Hodgkin＇s lymphoma（NHL） cases verified by pathology were analyzed. Three cases involved the maxillary region and one case occurred at the bilateral maxilla and mandible. All CBCT imaging findings possessed the features of ill-defined borders and osteolytic regions. However, the extent of bone destruction varied. The panoramic images of two cases also exhibited bony changes. Although both CBCT and panoramic findings of NHL demonstrate general malignant features, its variety of jaw change deserves further study.
