In this report seven cases of diffusely altered signal intensity of the posterior cruciate ligament (PCL) at magnetic resonance imaging (MRI) are described. The abnormalities resemble those of mucoid degeneration of the anterior cruciate ligament (ACL) and are associated with it in six cases. Although mucoid degeneration of the ACL is an increasingly reported entity, with well-established imaging criteria at MRI, to the authors' knowledge similar findings were never described before for the PCL. It is hypothesized that these abnormalities of the cruciate ligaments are similar in nature, probably related to degenerative changes of the connective tissue.
本报告描述了7例磁共振成像（MRI）显示后交叉韧带（PCL）信号强度弥漫性改变的病例。这些异常类似于前交叉韧带（ACL）黏液样变性的表现，6例中与ACL黏液样变性相关。虽然ACL黏液样变性的报道日益增多，MRI上有明确的成像标准，但据作者所知，此前从未有过PCL类似表现的描述。据推测，这些交叉韧带的异常本质上相似，可能与结缔组织的退行性改变有关。
