Neuroimaging features of multiple neurofibromas in a patient with neurofibromatosis type 1

Thirty-two-year-old with multiple neurofibromas involving the posterior tibial and peroneal nerves. (A) Sagittal T1-weighted, (B) sagittal fat-saturated T2-weighted, (C) transverse axial T2-weighted, and (D) postcontrast fat-saturated T1-weighted MRIs show the classic "target pattern" of neurofibromas, which is apparent both on T2- and postcontrast T1-weighted images. However, this pattern is not specific since schwannoma may also have this appearance.
