Magnetic resonance imaging of a left antecubital lesion. (a) Axial T2-weighted; (b) coronal T2-weighted; (c) sagittal short T1 inversion recovery; and (d) postcontrast T2-weighted image. All depict an enhancing (d) mass with ill-defined borders involving the radial nerve and surrounding musculature
