Lumbar X-rays and an MRI showed moderate degenerative disc disease at the L5-S1 level, a 3 mm minimal degenerative retrolisthesis, and a right paracentral L5-S1 disc protrusion causing moderate lateral recess narrowing [Figures 1 and 2].

She underwent an L5-S1 ALIF without complication [Figure 3].

She was given a steroid taper and sent for a lumbar CT scan that "suggested" encroachment on the left L5-S1 neural foramen by the L5-S1 ALIF [Figure 4].

Of interest, the MRI showed an intramedullary "lesion" at the L1-2 level in the area of the conus medullaris of unclear significance [Figure 5].

ALIF cage [Figure 6]. A neurologist performed an EMG of the left lower extremity and determined that her deficit was likely consistent with transverse myelitis and/or a poly-sensory neuropathy (i.e., bilateral superficial peroneal and sural nerves).
