📌Prepatellar Bursitis
- Fluid accumulation, synovitis, and bursal wall thickening in superficial bursae
- Causes anterior knee pain and swelling
✅ Etiology:
- Repetitive microtrauma (e.g., kneeling)
- Infection
- Gout
- Sarcoid
- CREST syndrome
- Immunocompromise
✅ MRI Findings:
- Well-defined, crescentic fluid collection in prepatellar soft tissues
- May show heterogeneous signal (hemorrhage or infection)
- Visible septa representing fibrous layers within bursae
✅ Superficial Bursitis:
- Better-defined, focal fluid accumulation
- Presents as an arc over patella, patellar tendon, or tibial tubercle
- May appear unilocular, bilaminar, or trilaminar due to communicating bursae
