Fig. 6

A 35 -year-old female with deep pelvic pain, Lt. groin pain and Lt. sciatica for 6 months with electrophysiological evidence of subacute left lumbosacral plexopathy. MR neurography showed Plexiform neurofibroma: Axial T2 (AC) and T2 SPAIR (DF) images through the pelvis show numerous hyperintense peripheral nerve sheath tumors which demonstrate the target sign (white arrow in D) involving the Lt. sciatic nerve (blue arrow in B), Lt. inferior gluteal nerve (red arrows in B and D), Lt. obturator nerve (white arrows in A and E) and Lt. pudendal nerve (white arrows in C and F). Coronal 3D VISTA images through the lower abdomen and pelvis (G and H) show diffuse enlargement of the Lt. sciatic nerve (white arrows in G), Lt. obturator nerve (white arrow in H) and Lt. pudendal nerve (red arrow in H) with multifocal lesions demonstrating the target sign. Post contrast images (I, J) show homogenous enhancement of the multifocal lesions (white arrows in I and J)
