Presentation
Low back pain
Patient Data
L4/5 wide-based posterior central disc protrusion with narrow base (disc extrusion), indenting ventral thecal aspect and partially encroaching upon lateral recesses.
L2 vertebral body hemangioma, expressing high T1 and T2 signal with coarse bone trabeculae. No loss of signal intensity between the in-phase and out-of-phase sequences.
The patient was managed by L5 spinolaminectomy decompressing thecal sac at the level of disc extrusion.
Size progression of L4/5 posterior central disc extrusion, with moderate spinal canal stenosis, partially encroaching upon lateral recesses and exit foramina.
L1 vertebral body hemangioma.
Case Discussion
This case shows the progression of disc extrusion size over one year period. Note the narrow neck of the herniated disc material and the wide dome.
There is also L2 vertebral body hemangioma that shows no loss of signal intensity between the in-phase and out-of-phase sequences as vertebral hemangiomas contain macroscopic fat stroma surrounding dilated vascular channels, not microscopic fat.
