•Mycetoma is a progressive destructive disease causing severe disability, if untreated.•This chronic granulomatous infection is characterized by the triad of tumor formation, presence of grains and draining sinuses.•Radiology is important in diagnosis and assessing the degree of extension.•The “dot-in-circle” sign provides early, noninvasive clue in diagnosis of mycetoma. Mycetoma is a progressive destructive disease causing severe disability, if untreated, in otherwise healthy people. Susceptible populations are usually adult males and disease is characterized by the triad of tumor formation, presence of grains and draining sinuses. Here, we report a case of mycetoma of a young female, manifested only as a painful swelling over left ankle which was initially suspected as a malignancy. The preliminary diagnosis of mycetoma came with the presence of characteristic “dot in circle” sign in radiological evaluation which was confirmed by the positive fungal culture of 2nd biopsy for M. mycetomatis.
