Malignant Peripheral Nerve Sheath Tumor: MRI and CT Findings

Figure 2

(a) Coronal STIR shows pelvic mass extending to the right S2 neuroforamen (long double arrows), right erector spinae/multifidus muscle neurofibroma (long big arrow) and small bilateral hip neurofibromas (short small arrows). (b) Coronal T1 shows pelvic mass extending to the right S2 neuroforamen (arrow). The other neurofibromas seen in (a) are not well visualized because their signal intensity is isointense to muscle. (c) Sagittal T2 FS shows pelvic mass (arrow points to right S2 neuroforamen).
