Coronal (A) T2-weighted MRI of the abdomen show a huge retroperitoneal
mass with partially well delineated margins and markedly heterogenous
intensity signal, causing upper displacement of the right kidney and
enlarging of neual foramina. Multiple subcutaneous, paraspinal and
pelvic plexiform neurofibromas with the characteristic target sign are
shown. Axial MRI demostrate a mostly homogeneous isointense
retroperitoneal mass in T1- weighted image (B) with peripheral
inhomogenous contrast enhancement after gadolinum intravenous
administration (C) and heterogenous diffusion restriction in diffusion-
weighted MRI (D) and ADC map (E).
