Ultrasound On Ganglion

:efinition Ganglion

Ganglion cysts are non-malignant cystic masses that occur in association with musculoskeletal structures . They are sometimes also simply referred to as ganglia or a ganglion, but should not be confused with the anatomical termganglion.

:Causes for Ganglion

The aetiology is yet to be known. Myxoid degeneration of fibrous tissue of capsule, ligaments and retinaculae has been suggested. This is sometimes initiated or excited by injury.
According to some, ganglion arrises from small bursa within the substance of the joint capsule or the fibrous tendon sheath. This bursa becomes distended possibly following trauma giving rise to a ganglion. Synovial herniation is the probable cause of ganglion has been rejected.

: Pathology

Ganglion is a cystic swelling containing clear gelatinous fluid or viscous fluid. It is surrounded by fibrous capsule and it posseses small pseudopodia






:efinition Ultrasound
Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It is used to help diagnose the
causes of pain, swelling and infection in the body’s internal organs and to examine a baby in pregnant women and the brain and hips in infants. It’s also used to help guide biopsies, diagnose heart conditions, and assess damage after a heart attack. Ultrasound is safe, noninvasive, and does not use ionizing radiation
.




:iagnosis of ganglion cysts
Ganglion cysts are diagnosed using a number of tests including
· Medical history
· Physical examination
· Ultrasound
· X-rays
· Needle aspiration (a fine needle is used to draw off fluid, which is then examined in a laboratory).


:Use of ultrasound on ganglion
The aim of this study was to demonstrate the use of ultrasound guidance in confirming intralesional injection of corticosteroids and local anesthetic into symptomatic ganglia, and to propose potential advantages of this technique. Design and patients. Ten patients (five men, five women) underwent ultrasound-guided injection of a ganglion. Seven ganglia were near the wrist, one was adjacent to a finger interphalangeal joint and two were adjacent to the talus. All were injected with a 1:1 mixture of long-acting corticosteroid and local anesthetic, the actual volume being dependent on the size of the ganglion. Three patients had a second injection 9–18 months following the initial injection. Results. In four patients the ganglia resolved completely. In five patients there was significant improvement, with a reduction in size of the ganglion and symptomatic relief. Conclusion. Ultrasound-guided injection insures intralesional deposition of corticosteroids and may provide an alternative to surgery in the management of ganglia .
