Case report: Dot-in-circle sign - An MRI and USG sign for "Madura foot"

Dot-in-Circle Sign - A Diagnostic MRI Sign for "Madura Foot".

Mycetoma is a slowly progressive localised, granulomatous, subcutaneous tissue infection common among adult males aged 20 - 50 years. The causing agents include both bacteria (actinomycetoma) and fungi (eumycetoma). This chronic infection was described in literature as Madura foot and eventually mycetoma, due to its etiology. Early clinical diagnosis before the appearance of sinuses and grains ...

The dot-in-circle sign of mycetoma on MRI.

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 (M...

Experimental Treatment of a Suspected Case of Mycetoma Based on Dot-in-Circle Sign

Mycetoma (Madura foot): A case report.

INTRODUCTION Mycetoma is a chronic disease, which is endemic in tropical and subtropical countries. We report a rare case of mycetoma located on the foot of a patient living in a temperate-climate country followed by a short discussion.

Madura foot masquerading as a hemangioma

Mycetoma, also known as Madura foot, is a rare soft-tissue granulomatous infection caused by Actinomyces or true fungi. The MRI "dot-in-circle" sign has been described as a characteristic finding of mycetoma. This sign represents spherical T2 bright masses containing central and intervening low-signal-intensity foci. However, other soft-tissue masses can have similar appearances. We present a c...
