A 42-year-old farmer was lifting a hay bale and experienced a sudden onset of sharp pain radiating down his left leg. Over the ensuing week, the pain became less pronounced, but was replaced with a progressive left greater than right leg numbness, foot weakness, and urinary hesitancy. He presented to his local hospital, where he was initially managed conservatively, and then transferred to our institution for consultation after an MR lumbar spine was completed. On physical exam, he had grade 1/5 weakness of left and right dorsi- and plantar flexion. Sensory testing showed a moderate decrease in pinprick sensation in his left leg from L1 to S1 dermatomes. He was symmetrically hyporeflexic with grade 1 knee reflexes and absent ankle jerks. Peri-anal sensation was intact, but there was moderately reduced rectal tone. The remainder of his neurological exam was normal.
