A patient is presented with solid aneurysmal bone cyst of the left proximal femur and a pathologic bone fracture in this region. The radiological and histological features of this lesion are described. While a conventional aneurysmal bone cyst is an expanding osteolytic lesion consisting of blood-filled spaces of variable size, separated by connective tissue containing bone trabeculae or osteoid tissue and many osteoclastic giant cells, a solid aneurysmal bone cyst is an unusual solid bone lesion with fibroblastic, osteoclastic, osteoblastic, aneurysmal, and fibromyoxid elements. The differential diagnosis includes giant cell tumor and fibroblastic osteosarcoma as well as specific bone reactions (bone fracture, reparative giant cell granuloma in hyperparathyroidism, giant cell reaction of short tubular bones). Solid aneurysmal bone cyst is a tumor-like lesion and probably a special bone reaction to damage; it has a good prognosis. Usually curettage is curative.
一名患者被诊断为左股骨近端实性动脉瘤样骨囊肿，并伴有该区域的病理性骨折。本文描述了该病变的放射学和组织学特征。传统的动脉瘤样骨囊肿是一种膨胀性溶骨性病变，由大小不一的充满血液的腔隙组成，腔隙被含有骨小梁或类骨组织以及许多破骨巨细胞的结缔组织分隔；而实性动脉瘤样骨囊肿是一种罕见的实性骨病变，含有成纤维细胞、破骨细胞、成骨细胞、动脉瘤样及纤维黏液样成分。鉴别诊断包括骨巨细胞瘤、纤维母细胞性骨肉瘤以及特定的骨反应（骨折、甲状旁腺功能亢进中的修复性巨细胞肉芽肿、短管状骨的巨细胞反应）。实性动脉瘤样骨囊肿是一种肿瘤样病变，可能是对损伤的一种特殊骨反应；其预后良好。通常刮除术即可治愈。
