多发性骨巨细胞修复性肉芽肿(2例报告并文献复习)

目的 探讨颌骨外特别是长管状骨多发性骨巨细胞修复性肉芽肿的X线诊断。材料与方法 经手术病理证实的骨巨细胞修复性肉芽肿2例,其中1例为累积多个长管状骨的多发病变。2例均摄X线平片,并连续数年观察其变化。结果 X线平片主要表现为明显膨胀,骨皮质变薄,无骨膜反应,无软组织肿块,病灶内可见或多或少的点状致密影。主要特征为病灶多发性以及同一时期不同病灶的不同X线表现。结论 骨巨细胞修复性肉芽肿是一种比较少见的疾病,特别是发生在长管状骨,其诊断有一定难度。当病灶为多发和同一病灶既有破坏又有修复时应想到本病的可能。

Multiple Giant Cell Reparative Granuloma of Bone

Objective To study the X ray diagnosis of multiple giant cell reparative granuloma (MGCRG) in the long tubular bones.Materials and Methods Two cases of pathologically proved MGCRG were collected. The lesions involved several long tubular bones in one case.Results MGCRG in jaw was manifested as marked expansive lesion and thinned periosteum without periosteal reaction or soft tissue mass, more or less spotted dense shadows within the lesion, while MGCRG in long bones was characterized by multiple foci and different signs of different lesions. Conclusion MRCGR, especially in the lone tubular bones, is a rare disease. It is somewhat difficult to make a correct diagnosis, but MGCRG should be considered when the lesion is multiple and when both destruction and repair are seen within one focus.
