a-d: MRI shows a mass originating from the ileum and extending into the soft tissues both anteromedially and posterolaterally. In T1-weighted sequences the mass is isointense with muscle (a). It enhances after administration of gadolinium (b, c). In fat-suppressed T2-weighted sequences it has high signal intensity (d).
