MR IMAGING OF PERIPHERAL NERVE SHEATH TUMORS OF THE EXTREMITIES
Keywords:
Nervous system, neoplasm Nerves, peripheral, MRAbstract
Two patients with peripheral nerve sheath tumors (PNST) of the extremities were presented, emphasizing on magnetic resonance (MR) imaging findings. In both cases, T2-weighted images showed inhomogeneously hypersignal intensity and con- trast enhanced studies revealed intense enhancement predominantly at periphery. An oval shape or tapering of longitudinal end of the mass suggest its extension along longi- tudinally oriented structure such as neurovascular bundle.
