56 year-old the female with lumbago There is straightening of the lumbar alignment. A intraosseous hemangioma is noted in the L1 vertebral body. There is no evidence of compression fracture or joint subluxation.T11-12, T12-L1: There is no central canal or neural foramen stenosis.L1-2, L2-3: There is no central canal or neural foramen stenosis.L3-4: There is diffuse disk bulge and bilateral mild facet degenerative change. There is no central canal or neural foramen stenosis. L4-5: Vacuum phenomena in L4-5 intervertebral disk. There is diffuse disk bulge. A large soft tissue density lesion is noted along the dorsal side of the L5 vertebral body, causing compression to the thecal sac and left side exiting nerve root. It is measuring 17 x 8 x 24mm. No associated bone destruction. On sagittal images, it is contiguous with the L4/5 intervertebral disk (image 31 series 80269). However, other etiology such as meningioma can not be completely excluded given relative poor soft tissue contrast on CT images. A MRI study may help further evaluate. L5-S1: there is no central canal or neural foramen compromise.
1. L4/5 canal soft tissue density lesion, most likely extruded disk with inferior migration. However, other etiology such as meningioma can not be completely excluded given relative poor soft tissue contrast on CT images. A MRI study may help further evaluate. It causes central canal stenosis and nerve root impingement on the left.2. Mild degenerative disk disease in the lumbar spine. See details above.
