- Moderate joint effusion with gross synovial thickening showing frondlike projections that demonstrate hyperintense T1 and T2 signal with PD FAT SAT & STIR signal suppression.
- Mucoid degeneration of the ACL with celery stalk appearance showing increased signal intensity alternating with its normal hypointense fibers.
- Degenerative tear of the PHMM & AHMM with increased intrameniscal signal disrupting their articular surfaces.
- Normal heights and signal intensity of the lateral meniscus with no evidence of meniscal tear.
- Intact posterior cruciate and collateral ligaments.
- Degenerated articular cartilage with osteoarthritis of the knee joint with as well as tibio-femoral and patellofemoral articular osteophytosis & subchondrtal degenerative marrow changes.
- Normal signal and girth of the examined periarticular musculature.
- Small prepatellar bursitis is noted.
Case Discussion
Lipoma arborescens of the knee joint with
moderate joint effusion, mucoid degeneration of the ACL, degenerative tear of the
PHMM and AHMM as well as osteoarthritis of the knee joint and small prepatellar bursitis
