Focal weakness and hip flexors and medial thighs, known iliopsoas abscess but recently drained Examination slightly motion degraded.Thoracic: Thoracic vertebral body heights are maintained. Alignment is maintained. Thoracic spinal canal is mildly narrow on a congenital basis. There are minimal degenerative changes without significant spinal canal or neural foraminal stenosis. Thoracic cord is normal in signal and contour. Bone marrow signal is benign with no suspicious lesions. T1 hyperintense focus at T10 is compatible with focal fat or hemangioma.Lumbar:Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is mild loss of lumbar lordosis. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.There is moderate loss of disc height at the L5-S1 level with associated endplate changes. The spinal canal appears congenitally narrow, worse inferiorly, with superimposed degenerative changes as described below: L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: There is mild spinal canal stenosis, predominantly on a congenital basis. No significant disc disease. No neural foraminal stenosis.L3-L4: There is mild spinal canal stenosis, predominantly on a congenital basis and prominence of the epidural fat. There is mild disc desiccation with small right foraminal disc protrusion which contacts the exiting right L3 nerve root without clear impingement. No significant left neural foraminal stenosis.L4-L5: There is moderate spinal canal stenosis, predominantly on a congenital basis, prominence of the epidural fat, as well as a superimposed ligamentum flavum thickening, mild disc bulge with annular fissure. Minimal bilateral foraminal narrowing.L5-S1: There is narrowing of the spinal canal which is predominantly on a congenital basis with superimposed prominence of the epidural fat and mild degenerative changes including disc desiccation, ligamentum flavum thickening, mild disc bulge and endplate osteophytes. No significant foraminal stenosis.Fluid collections along the bilateral iliopsoas musculature are noted. There is a discrete approximately 3 x 3 cm fluid collection on the right.
1. No significant spinal canal stenosis in the thoracic spine or thoracic cord signal abnormality.2. Moderate stenosis of the lumbar spinal canal at L4-L5 and L5-S1 which is predominantly on a congenital basis with mild superimposed degenerative changes and prominence of the epidural fat. There is mild narrowing of the right L3-L4 neural foramen. Otherwise no significant neural foraminal stenosis is appreciated.3. Fluid collections along the bilateral iliopsoas musculature are partially visualized. There is an approximately 3x3 cm right iliopsoas fluid collection which may be impinging on the peripheral course of the lumbar nerve roots on the right. Please note evaluation for infection can be better obtained with postcontrast sequences; however no obvious evidence of discitis-osteomyelitis or epidural extension of infection is demonstrated.
