Michael H. Ngo MD, Abstract Co-Author: Nothing to Disclose

Identify the imaging characteristics of peripheral nerve sheath tumors (PNST) and neuromas Review the anatomic distribution of the major lower extremity nerves with description of important distal branch nerves Describe the muscle denervation pattern in specific muscle compartments based on the location of the PNS

Anatomic review of the major lower extremity nerve distributions and their muscular innervation MRI Pictoral Review of biopsy proven peripheral nerve sheath tumors* and neuromas of each of the major lower extremity nerves. femoral nerve (3 cases) -- *1 case involving the femoral nerve was the exception that was thought  initially to represent a PNST but was histologically proven to be a sarcoma obturator nerve tibial nerve (2 cases proximal and distal) Sciatic nerve (stump neuroma status post above knee amputation) 1 case of inferior gluteal nerve common peroneal nerve deep peroneal nerve superficial peroneal nerve intermetatarsal plantar nerve
