Figure 1

Magnetic resonance imaging (MRI) showed a lobulated multiseptated lesion seen within left supinator muscle as delineated by the red arrows, which showed a hyperintense signal on T2-weighted images (T2WI) (b, e) and hypointense on T1-weighted images (T1WI) (a, d), with peripheral enhancement post contrast (c).
