Axial T1 image of the foot demonstrating round and serpiginous intermediate-signal-intensity masses in the lateral subcutaneous tissues, Some of the masses have internal areas of low T1 signal.

The masses displayed low signal intensity on T1 and high signal intensity on T2 and STIR sequences, with some intervening and central foci of low T1-, T2-, and STIR-signal intensity (Figure 1, Figure 2, Figure 3, Figure 4).
Axial STIR image demonstrates the "dot-in-circle" sign described in mycetoma (arrow).

The masses displayed low signal intensity on T1 and high signal intensity on T2 and STIR sequences, with some intervening and central foci of low T1-, T2-, and STIR-signal intensity (Figure 1, Figure 2, Figure 3, Figure 4).
Axial T1 fat-suppressed image, post contrast, demonstrates enhancement of the mass involving the lateral soft tissues of the foot and "dot-in-circle" sign (arrow).

The masses displayed low signal intensity on T1 and high signal intensity on T2 and STIR sequences, with some intervening and central foci of low T1-, T2-, and STIR-signal intensity (Figure 1, Figure 2, Figure 3, Figure 4).
Sagittal T1 fat-suppressed postgadolinium image at the lateral aspect of the ankle and foot demonstrates a large enhancing mass containing spherical and serpiginous components that contain both central and intervening areas of low signal.
