(Redirected from Ganglion Cyst (Main))
Other Names
- Note: Not to be confused with anatomic term ganglion
Background
- Locations
- Wrist: Ganglion Cyst of Wrist
- Represent up to 80% of cases
- Knee
- Spinoglenoid Notch
- Ankle
- Foot
- Wrist: Ganglion Cyst of Wrist
- Types
- Intramuscular
- Intrameniscal
- Intratendinous
- Intraosseus
Pathophysiology
- Etiology is not entirely clear
- Proposed pathophysiology
- Myxoid degeneration of connective tissue in joint capsules, tendon sheaths[1]
- Typically remain attached to their anatomic origins
- Causes
- Degenerative
- Trauma
- Sports
- Post surgical
- Histology
- Thin connective tissue without a synovial lining
- Filled with gelatinous fluid rich in hyaluronic acid, mucopolysaccharides, glucosamine, globulins, and albumen[2]
Risk Factors
Differential Diagnosis
Clinical Features
Evaluation
- Radiographs[3]
- Not necessary in diagnosis, may exclude other etiology
- Ultrasound
- Well defined margins on ultrasound, internal septations, acoustic enhancement
- Can help differentiate from aneurysm
- Useful for procedural aspiration
- MRI
- Not routinely required to make diagnosis
- May or may not be loculated
- Adjcent to tendon sheath or joint
Classification
- Osseus
- Within bone
- Adjacent to bone
- Away from bone
- Joint
- Within joint
- Adjacent to joint
- Structure
