Mycetoma is a chronic granulomatous disease prevalent in tropical countries, but it also occurs in Europe and the United States. Early diagnosis is important as it has therapeutic implications. Although biopsy and microbiological culture provide the definitive diagnosis, these are difficult to achieve in many instances. The dot-in-circle sign is a recently proposed magnetic resonance imaging (MRI) sign of mycetoma, which is likely to be highly specific. We present a case of mycetoma of the thigh with characteristic MRI features. To the best of our knowledge, only 2 cases of mycetoma of the foot demonstrating this sign have been previously published.
足菌肿是一种在热带国家流行的慢性肉芽肿性疾病，但在欧洲和美国也有发生。早期诊断很重要，因为它具有治疗意义。尽管活检和微生物培养可提供确诊依据，但在许多情况下难以实现。“圆圈内点征”是最近提出的足菌肿的磁共振成像（MRI）征象，可能具有高度特异性。我们报告一例具有特征性MRI表现的大腿部足菌肿病例。据我们所知，此前仅发表过2例显示该征象的足部足菌肿病例。
