Overview

MRI may be helpful in the diagnosis of neurofibroma. It appears as a hypointense, homogeneous low signal intensity lesion with center demonstrating a higher signal intensity than the periphery on T1. T2 weighted images show hyperintense, homogeneous lesion with positive target sign and fascicular sign. Moreover, neurofibromas have heterogeneous enhancement on T1 C+ (Gd) (with gadolinium contrast).
