Minimal anterior slippage of L5 over S1 vertebra secondary to bilateral L5 pars interarticularis defect with mild L5-S1 pseudodisc bulge not compromising the neural foramina
From the case:
Spondylolysis and spondylolisthesis

The black circle refers to the defect in pars interarticularis.
Case Discussion
Pars interarticularis defect occurs following stress or repetitive microtrauma. Bilateral pars fracture may lead to spondylolisthesis with the vertebra slipped on the vertebra below dragging its nerve root against the normally placed disc (so-termed pseudobulge) which results in patient's symptomatology.
