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

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

The “dot-in-circle” sign in musculoskeletal mycetoma on magnetic resonance imaging and ultrasonography

This study aimed to present the 'dot-in-circle' sign, which indicates the typical magnetic resonance imaging (MRI) and ultrasonographic (USG) findings for mycetoma involving soft tissue and bone. A total of 8 cases with histopathological proof of mycetoma affecting the musculoskeletal system, and that were examined via MRI and/or coexistent diagnostic ultrasonography between 2004 and 2013 in So...

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...

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 ...

Isolation of both Pseudozyma aphidis and Nocardia otitidiscaviarum from a mycetoma on the leg.

We describe a case of mycetoma which typified the classic presentation of the disease: a male farmer with affection of the lower limbs and a history of trauma. The patient presented with a swollen right lower limb showing multiple discharging sinuses for 25 years. Histopathologically, grains were found by HE stain, and clustered yeast-like cells were observed by PAS stain. The distinctive 'dot-...
