Asymptomatic traumatic neuroma

Abstract

A rare case of asymptomatic traumatic neuroma, triggered by the performed amputation within the right thigh due to the osteosarcoma is reported. The MRI examination has shown a focal lesion at the end of the sciatic nerve, with isointense signal and weak contrast enhancement on T1-, high signal on T2-weighted images, without restriction diffusion on DWI. The morphology did not significantly change after 12 months, which confirms the primary diagnosis. The main limitation of the case is the lack of histological confirmation, since the lesion was not removed.
