Gout is characterized by the deposition of monosodium urate (MSU) crystals with negative birefringence under polarized light in synovial fluid and joint regions. This results in the development of chronic inflammatory arthritis, typically in the first metatarsophalangeal, talar, subtalar, ankle, and knee joints. Although less common, an underrecognized feature of gout is extraarticular deposition, such as in the abdomen. This case report describes the presence of a gouty abdominal mass in a 66-year-old male with prior history of gout. We exhibit our imaging findings and discuss the importance of keeping gout in the differential when an unknown abdominal mass is found.
痛风的特征是在偏振光下，滑液和关节区域出现具有负双折射的尿酸钠（MSU）晶体沉积。这会导致慢性炎症性关节炎的发展，通常累及第一跖趾关节、距骨、距下关节、踝关节和膝关节。虽然不太常见，但痛风一个未得到充分认识的特征是关节外沉积，比如在腹部。本病例报告描述了一名有痛风病史的66岁男性患者出现痛风性腹部肿块的情况。我们展示了影像学检查结果，并讨论了在发现不明腹部肿块时，将痛风纳入鉴别诊断的重要性。
