Cysts & masses
Baker’s cysts, meniscal cysts, and other periarticular masses
Not every lump is a tumor. Many are cysts linked to internal inflammation. I diagnose the cause and treat the origin to prevent recurrence.
Imaging diagnosis
Ultrasound or MRI to define cyst vs solid mass.
How they show
- • Tight lump behind the knee (Baker cyst).
- • Cyst near the meniscus with pain or catching.
- • Soft masses around tendons or ligaments.
- • Volume that appears/disappears with activity.
Ultrasound or MRI differentiates cysts from solid lesions and finds any intra-articular cause.
Treatment
- • Treat the origin (synovitis, torn meniscus, arthritis).
- • Guided aspiration in selected cases.
- • Arthroscopy to solve internal causes of the cyst.
- • Open surgery only when necessary with clear diagnosis.
Goal: relieve pain, avoid recurrence, and preserve knee function.
When to consult
If the lump hurts, grows, limits motion, or recurs after draining, book a visit. I’ll determine if it’s benign or needs further workup.
