73 years Male (DOB:6/30/1942)Reason: DDD History: back painPROVIDER/ATTENDING NAME: TARIQ MUSLIM MALIK TARIQ MUSLIM MALIK Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall alignment and height. The conus medullaris on sagittal imaging is grossly intact.At L5-S1 there is no significant compromise to spinal canal or neural foramina. There is loss of disc space height and a disc bulge present at this level associated with mild facet and ligamentum flavum hypertrophy.At L4-5 there is loss of disc space height, disc desiccation and diffuse disc bulge associated with superimposed disc extrusion. Extruded disc material extends behind the L4 vertebral body. Extruded material was not present on the prior exam. There is bilateral facet and ligamentum flavum hypertrophy present at this level which is more on the left the right side. There is left lateral disc present at this level which extends into the left neural foramen and mildly encroaches on the left-sided exiting nerve root within the left neural foramen. T2 signal hyperintensity along the left facet joint within the ligamentum flavum is suspected to represent a ligamentum flavum cyst. There is effacement of the fat at the lateral recess at this level bilaterally but more on the left compared to the right side. Overall there is a moderate degree of spinal stenosis present at this level.At L3-4 there is no significant compromise to spinal canal or neural foramina. There is mild ligamentum flavum hypertrophy present at this level.At L2-3 there is no significant compromise to spinal canal or neural foramina.At L1-2 there is no significant compromise to spinal canal or neural foramina.
1.Since the prior examination the patient is developed a matted disc extrusion at the L4-5 level. There is a moderate degree of spinal stenosis present at L4-5 which appears slightly worse on the current exam compared to the prior exam as detailed above. There is some mild encroachment on the left-sided exiting nerve root at L4-5 due to disc disease.
