Giant cell tumor (GCT) of bone is a benign, locally aggressive lytic lesion in the subarticular location occurring in skeletally mature individuals. Acute hemarthrosis from pathological fracture of GCT should be considered in the differential diagnosis for acute swelling of the knee. Here we describe the imaging appearances of GCT on conventional radiography and magnetic resonance imaging (MRI).
骨巨细胞瘤（GCT）是一种发生于骨骼成熟个体的关节下部位的良性、局部侵袭性溶骨性病变。骨巨细胞瘤病理性骨折导致的急性关节积血应列入膝关节急性肿胀的鉴别诊断中。在此，我们描述骨巨细胞瘤在传统X线摄影及磁共振成像（MRI）上的影像表现。
