Introduction. Tophaceous gout of the patella is rare and may masquerade as a tumour or tumour-like condition. Cases. We report two patients with gout involving the patella, one complicated by a pathological fracture and the other occurring in a bipartite patella in a young adult. Discussion. Typical imaging appearances and measurement of serum urate will usually confirm the diagnosis but, occasionally, the serum urate level may be normal in active gout and in such cases, a biopsy will be required. Conclusion. Gout of the patella may masquerade as a tumour or tumour-like condition and it is important to consider gout in the differential diagnosis.
引言。髌骨痛风石性痛风较为罕见，可能会伪装成肿瘤或肿瘤样疾病。病例。我们报告了两名累及髌骨的痛风患者，其中一名并发病理性骨折，另一名发生在一名年轻成年人的二分髌骨中。讨论。典型的影像学表现和血清尿酸盐测量通常可以确诊，但在活动性痛风中，血清尿酸盐水平偶尔可能正常，在这种情况下，需要进行活检。结论。髌骨痛风可能会伪装成肿瘤或肿瘤样疾病，在鉴别诊断中考虑痛风很重要。
