This case involves a 48-year-old male who underwent a micro-discectomy at L3-L4. Immediately following the procedure, the patient experienced numbness in his legs along with the inability to void his bladder. An MRI was performed the day after surgery and revealed a large extradural defect at L3-L4 juncture, which was consistent with a large central disc herniation. A second surgery was performed the following day that revealed a calcified annulus with resultant stenosis and compression of the thecal sac. The second surgery did not relieve that patient’s symptoms and he is currently non-ambulatory and wheelchair bound. The final diagnosis was severe cauda equina with foot drop.
