Presentation
Non-specific low back pain, no radicular pain
Patient Data
Mild degenerative changes involving L3-S1 levels - disc bulging.
Fat containing mass within the right L3-L4 intervertebral joint with a signal loss on both STIR and T1 fat-saturated images leading to the right subarticular zone and mild dural sac stenosis.
Mild intervertebral osteoarthritic changes.
Case Discussion
Mentioned above findings are consistent with a rare appearance of the intra-articular intervertebral synovial lipoma.
Despite dural sac and subarticular zone stenosis, there are no specific symptoms.
STIR sequence doesn't exclude lipoma due to the T1 shortening effect. T1 fat-saturated images show typical features of the lipoma.
At our knowledge, there are no such reports in the international literature.
