47 year old male truck driver presenting with low back pain associated with left leg weakness and numbness.
He had been normal prior to acute onset of symptoms several days prior to presentation. His symptoms started while driving. He denied any specific injury or doing any heavy lifting. His symptoms rapidly worsened over the following hours to the point where he was having difficulty walking and felt like his “left leg fell asleep and never woke up.” He had no recent infectious symptoms.
He took an appointment for initial evaluation. Basic labs and a lumbosacral x-ray were obtained.
He was referred to the physiotherapy dept. several days later. At that time, his back pain was improving. However, he continued to have symptoms down his left leg. He was now ambulating with a cane and had fallen several times. Visible atrophy of his left thigh muscles were noticed.
He had no history of malignancy, diabetes, or thyroid disease. He denied fevers, chills, saddle anesthesia, bowel/bladder issues, or IV drug use.
