Abstract

A 60-year-old gentleman had presented to our clinic, with one-year duration of symptoms in the posterior aspect of the left thigh exacerbated by sitting. NCV/EMGs of bilateral lower extremities were within normal limits. MRI of the lumbosacral spine did not reveal neuroforaminal stenosis. MRI of the pelvis showed a hypertrophied piriformis on the left side causing entrapment of the S1 and S2 nerve roots.
