Presentation
Severe lower back pain, worsening with degenerative facets on MRI ? facet joints amenable to injection. L3-5 laminectomy.
Patient Data
Procedure: A 3 phase bone scan and SPECT/CT of the lumbar spine and pelvis were performed following IV injection of 800 MBq of Tc-99m MDP.
No blood flow or blood pool abnormality in the lumbar spine.
There is mild degenerative osteoblastic activity at the L5/S1 endplates.
Mildly increased osteoblastic activity at the L4/5 right facet joint.
Photopenia of the superior left femoral head correlates to geographic sclerosis on CT compatible with avascular necrosis.
L3-5 laminectomy with minor retrolisthesis at L5/S1.
Incidental note of mild, uncomplicated diverticular disease.
Case Discussion
Mild degenerative osteoblastic activity at L5/S1. Mild osteoblastic activity associated with L4/5 right facet arthropathy. Left femoral head avascular necrosis.
