Mycetoma or Maduramycosis is a chronic granulomatous infectious condition encountered mostly in tropical and subtropical regions. It affects the deep subcutaneous tissues, which may progress to involve the muscles and bones later in the course of the disease. It can be caused by fungi (eumycetoma), and bacteria (actinomycetoma) predominantly affecting the foot. Demonstration of the causative agent by biopsy and microbiological studies helps to establish a confirmative diagnosis, and choosing correct antimicrobial therapy. However, it may be delayed resulting in increased patient morbidity. Thus, imaging plays a vital role in early recognition & prompt treatment, especially MRI which is a non-invasive procedure demonstrating the hallmark dot in circle sign. Here we report a case of mycetoma foot with pathognomic MRI findings.
足菌肿或马杜拉足菌肿是一种慢性肉芽肿性感染性疾病，多见于热带和亚热带地区。它影响深部皮下组织，在疾病进程后期可能进展至累及肌肉和骨骼。其可由主要影响足部的真菌（真菌性足菌肿）和细菌（放线菌性足菌肿）引起。通过活检和微生物学研究证实病原体有助于确诊并选择正确的抗菌治疗。然而，这可能会延迟，导致患者发病率增加。因此，影像学在早期识别和及时治疗中起着至关重要的作用，尤其是磁共振成像（MRI），它是一种无创检查，可显示典型的“靶征”。在此，我们报告一例具有典型MRI表现的足部足菌肿病例。
