Neurofibroma in a 53-year-old male with a painless left thumb nailbed swelling of 4–5-year duration. The patient had no personal or family history of neurofibromatosis or any other clinical manifestations, and this was likely an isolated lesion. (a) T1w sequence shows a lobulated subcutaneous lesion at the tip of the thumb, isointense to muscle involving the skin, with mild pressure erosion on the underlying distal phalanx (arrow). (b) The nodule is heterogeneously hyperintense on T2w-FS sequence. (c) Fairly homogeneous enhancement is seen
