The aim of this review is to describe the clinical, histopathologic, and MRI features of aseptic lymphocytic vasculitis-associated lesions in total hip replacements.
The introduction of modern metal-on-metal hip arthroplasty has been accompanied by a newly described disease, aseptic lymphocytic vasculitis-associated lesions, which is characterized histologically by bland necrosis and dense perivascular lymphocytic infiltrates. Conventional radiographic findings are often normal, but the typical MRI findings include periprosthetic fluid collections, soft-tissue masses, gluteal tendon avulsion, bone loss, periosteal stripping, neurovascular involvement, and periprosthetic fractures. The severity of the histologic and MRI appearances can be graded according to defined published criteria.
本综述旨在描述全髋关节置换术后无菌性淋巴细胞血管炎相关性病变的临床、组织病理学和 MRI 特征。
随着现代金属对金属髋关节置换术的引入，出现了一种新描述的疾病，即无菌性淋巴细胞血管炎相关性病变，其组织学特征为温和性坏死和密集的血管周围淋巴细胞浸润。常规放射学表现通常正常，但典型的 MRI 表现包括假体周围积液、软组织肿块、臀肌腱撕脱、骨丢失、骨膜剥离、神经血管受累和假体周围骨折。根据已发表的标准，可以对组织学和 MRI 表现的严重程度进行分级。
