Reason: please assess mass over right tbia; any evidence of vascular disease? History: young man with NF1 and moderate sized neurofibroma over tibia; he also has prominent varicose veins There is a focal well-defined ovoid mass abutting the anterior lateral aspect of the mid tibial metaphysis, which appears isointense to muscle on T1-weighted imaging and hyperintense on the STIR sequence. There is perhaps slight enhancement and the mass measures approximately 2.1 x 1.1 cm in its axial dimensions.
Mass abutting the anterior lateral aspect of the mid tibial metaphysis consistent with a neurofibroma.
