Aneurysmal bone cysts are benign active or aggressive bone tumors that commonly arise in the long bones, especially the femur, tibia, and humerus and the posterior elements of the spine. Aneurysmal bone cysts affect all age groups but are more common before skeletal maturity (first two decades of life). They usually involve the metaphysis or metadiaphyseal region of long bones. Although juxtaphyseal lesions abutting the growth plate and extending into the epiphysis have been described, there is no report of an aneurysmal bone cyst entirely and primarily located in the epiphysis. We report on a 3-year-old boy who presented with an entirely contained aneurysmal bone cyst to the proximal tibial epiphysis. We discuss the clinical presentation, diagnosis, including imaging and pathology, and treatment. A review of the pertinent literature also is presented.
骨巨细胞瘤是一种良性活跃或侵袭性骨肿瘤，常见于长骨，特别是股骨、胫骨和肱骨以及脊柱的后段。骨巨细胞瘤影响所有年龄段，但在骨骼成熟前（生命的头二十年）更为常见。它们通常累及长骨的干骺端或骨干骺端区域。虽然已经描述了毗邻生长板并延伸到骨骺的骺侧病变，但没有完全位于骨骺且主要位于骨骺的骨巨细胞瘤的报道。我们报告了一例 3 岁男孩，其胫骨近端骨骺完全被包含在骨巨细胞瘤中。我们讨论了临床表现、诊断，包括影像学和病理学以及治疗。还对相关文献进行了回顾。
