Figure 2. (a) Axial T2 weighted image with fat saturation (repetition time (TR) 5100 ms; echo time (TE) 60 ms) through the lower pelvic region showing an inhomogeneously multinodular hyperintense mass (white arrowheads) in the lowest segment of the right rectus abdominis muscle. (b) Axial T1 weighted image (TR 550 ms; TE 17 ms) demonstrating the same mass in the right rectus abdominis muscle (black arrowheads), which is nearly isointense to surrounding normal muscular tissue. (c) Axial T1 weighted image (TR 550 ms; TE 17 ms) with fat saturation again demonstrating the mass which is isointense to surrounding muscle and splaying surrounding vessels (arrowheads). (d) Axial T1 weighted image (TR 550 ms; TE 17 ms) after intravenous gadolinium contrast medium administration showing marked but inhomogeneous contrast enhancement of the mass in the right lower rectus abdominis muscle.
