At L3-4 there is a small central disc extrusion. Adjacent and inferior to the disc filling the left lateral recess, is a well defined oval 12 x 7 x 12 mm lesion which is mildly T1 hyperintense, markedly T2 hyperintense with rim enhancement. Focal central small T2 hypointensity within the lesion either gas or proteinaceous fluid. The lesion appears to communicate with the extruded disc. The subjacent L4 nerve root is displaced and compressed in the subarticular recess.
At L5-S1 a small/moderate sized central/right paracentral disc protrusion contacting and displacing the right S1 nerve root. Tiny cyst posterior to the disc within the lateral recess.
