Foreign body granulomas are common in the hand and foot. Diagnosis of the same is often delayed or missed, especially in unusual locations and in the paediatric age group. Radiographs usually reveal an osteolytic lesion with absence of periosteal reaction and non-metallic foreign bodies are not visualised in plain radiographs. An ultrasound and MRI can delineate the foreign body. Clinical and radiological presentation mimics that of a tumour and hence is rightly called pseudotumour. We present a case of thorn-induced pseudotumour of the fibula in a 5-year-old boy.
异物肉芽肿在手足部位较为常见。其诊断常常延迟或被漏诊，尤其是在不寻常的部位以及儿童年龄组中。X线片通常显示为溶骨性病变，无骨膜反应，且在普通X线片中无法显示非金属异物。超声和磁共振成像（MRI）可以明确异物。其临床和放射学表现类似于肿瘤，因此被恰当地称为假肿瘤。我们报告一例5岁男孩因刺引起的腓骨假肿瘤病例。
