A 22-year-old man is referred to the orthopaedic surgeon. He has pain, mostly at night, in his proximal right tibia that greatly reduces with NSAIDs. The CT scan shows a focal lucent zone, called a nidus, in the tibia cortex, surrounded by reactive, sclerotic bone. This is typical for an osteoid osteoma, a benign bone tumour.

一名22岁男子被转诊至骨科医生处。他的右胫骨近端疼痛，主要在夜间发作，服用非甾体抗炎药后疼痛大幅减轻。CT扫描显示胫骨皮质有一个局灶性透亮区，称为骨样骨瘤巢，周围是反应性硬化骨。这是骨样骨瘤的典型表现，骨样骨瘤是一种良性骨肿瘤。
