Meniscal cysts are common lesions, but extensive bony changes arising from these cysts are exceedingly rare. These changes are usually erosive defects about the tibia. Dull pain with an associated mass are classic findings. Magnetic resonance imaging is useful in making the diagnosis and arthroscopic management yields excellent results. A 47-year-old man developed a symptomatic medial meniscal cyst that invaded the medial femoral condyle simulating a solitary bone lesion. Magnetic resonance imaging revealed the contiguous nature of the cyst with the meniscus. Arthrotomy with cyst excision was required in this case and led to the amelioration of symptoms.
半月板囊肿是常见病变，但由这些囊肿引起的广泛骨质改变极为罕见。这些改变通常是胫骨的侵蚀性缺损。伴有肿块的隐痛是典型表现。磁共振成像有助于诊断，关节镜治疗效果良好。一名47岁男性出现有症状的内侧半月板囊肿，该囊肿侵犯内侧股骨髁，类似孤立性骨病变。磁共振成像显示囊肿与半月板相连。本例需要进行关节切开囊肿切除术，术后症状改善。
