We report a 44-year-old man who complained of low back pain and severe pain on the medial side of his right leg associated with a walking disturbance.
We diagnosed lateral lumbar disc herniation at the L4-5 level with findings from the physical examination, myelography and CT myelography consistent with this.
One week after these examinations, the patient complained of numbness on the lateral side of his right leg.
We performed magnetic resonance imaging (MRI), discography, CT discography, myelography and CT myelography.
These showed two pieces of disc material in the spinal canal and foramen.
Which were irritating the right L4 and L5 nerve roots.
We performed lateral fenestration and removed two pieces of disc material and an excellent surgical outcome was achieved.
