A patient with severe weakness,atrophy,and sensory loss of the right leg had a focal right sciatic neuropathy.The sciatic nerve was enlarged at the level of the lesser trochanter,excessively firm,and multistranded;its stimulation threshold was focally increased.Biopsied fascicles had reduplicated perineurial leaflets,many Renaut bodies,and an abnormal unimodal spectrum of small-diameter fibers.We postulate that the lesion was induced by the combination of an underlying prominent lesser trochanter and sitting on hard benches. |
