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.
