Dot in Circle Sign

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

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...

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 ...

‘Dot in circle sign’: a characteristic finding in ultrasound and MR imaging of soft tissue mycetomas

To cite: Neelakantan S, Babu AAS, Anandarajan R. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2016-216502 DESCRIPTION A 36-year-old man presented with a history of painless swelling on his right distal foot progressively increasing in size since 2 years. Physical examination revealed a non-pulsatile, non-tender, firm swelling over the medial aspect of distal r...

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...
