Meniscal cysts causing bone erosions are rare. The majority of meniscal cysts are associated with tears of the menisci and magnetic resonance (MR) imaging appearances are usually diagnostic. The MR images of a 34-year-old man showed a well-defined cystic mass that communicated with a horizontal cleavage tear of the posterior horn of the lateral meniscus and caused pressure erosion of the lateral tibial condyle. We believe this to be the first locally reported case of tibial erosion related to a meniscal cyst. This entity should be included in the differential diagnosis for a well-defined periarticular erosion.
引起骨质侵蚀的半月板囊肿很罕见。大多数半月板囊肿与半月板撕裂有关，磁共振成像表现通常具有诊断意义。一名34岁男性的磁共振图像显示一个边界清晰的囊性肿物，与外侧半月板后角的水平劈裂撕裂相通，并导致外侧胫骨髁的压力性侵蚀。我们认为这是本地首次报道的与半月板囊肿相关的胫骨侵蚀病例。这种情况应列入边界清晰的关节周围侵蚀的鉴别诊断范围。
