Here we report a 22year-old man who suffered from recurrent fever accompanied by chest and abdominal pain for more than 10 years. The attack frequency was about once per 23 weeks. Although he consulted many clinics and even received appendectomy at the age of 15, no definite diagnosis was given. During the admission, many laboratory examinations failed to show any abnormality except mild leukocytosis and elevated C-reaction protein. Image studies including chest X ray and abdominal CT scan showed negative result but, interestingly, Gallium-67 scan showed a hot spot in right lower chest and right lower abdomen. After prophylaxis with colchicines 1.0 mg per day, he has enjoyed more than 2 years without the above symptoms.

本篇报告发表一位22岁的男性，十余年来每隔二三周即发生周期性的发烧，浆膜炎；虽然他遍访数家医院，并且在十五岁时被诊断为阑尾炎，并接受开刀治疗，还是没有得到正确的诊断与治疗，此次住院当中，除了稍微的白血球与C-反应蛋白偏高以外，很多实验室检查皆正常，影像学检查包括胸部X光，腹部电脑断层均正常，但有趣的是Gallium-67扫描发现在右胸及右下腹出现强烈反应，经诊断为地中海热后给予秋水仙素预防性治疗，病人已经超过二年没有复发。
