概念-动脉瘤骨样囊肿是Jaffe和 Lichtenstein在1942年命名的。 是一种孤立性、膨胀性出血性、多房性囊肿,常在10~20岁发病。它们由被结缔组织分隔的充血的间隙组成,包括成纤维细胞,破骨巨细胞,反应骨。动脉瘤骨样囊肿分为原发性和继发性,后者多继发于骨巨细胞瘤、单纯性骨囊肿、 非骨化纤维瘤、骨母细胞瘤、软骨...
It is a very lytic, destructive lesion of bone occurring in patients between the ages of 10 and 20 years. Its characteristic feature is an aneurysmal appearance seen on X-ray that, in the early stages, is extremely destructive, osteolytic and permeative, taking on the radiographic features ...
