What is an intraosseous ganglion cyst?

Intraosseous ganglia are benign cysts that usually can be seen in lower extremity; especially around ankle. These cysts have fewer incidences in upper extremity, mainly around the wrist. They are extremely rare in olecranon. These lesions are often asymptomatic.

What does a ganglion cyst look like on a MRI?

On MRI, a ganglion cyst presents as a well-defined, unilocular or multilocular mass with a thin capsule. The contents are typically hypointense compared to skeletal muscle on T1-weighted images and hyperintense on water-sensitive (T2 or T2*-weighted, fat-suppressed intermediate weighted, or STIR) sequences (Figure 2).

Does ganglion cyst show up on MRI?

MRI. MRI is an accurate modality for the visualization and evaluation of ganglion cysts with a reported sensitivity and specificity of 94.7% and 94.4% 1,5. The typical appearance is that of a well-defined, multiloculated cystic lesion with a stalk.

What causes intraosseous ganglion cyst?

Intraosseous ganglion is a cystic lesion that contains gelatinous material, most often occurs in middle-aged patients, and is regarded as similar to soft-tissue ganglion. The etiology is unknown, but association with degenerative joint disease has been considered.

What is the best treatment for a ganglion cyst?

Treatment

  • Immobilization. Because activity can cause the ganglion cyst to get larger, it may help to temporarily immobilize the area with a brace or splint.
  • Aspiration. In this procedure, your doctor uses a needle to drain the fluid from the cyst.
  • Surgery. This may be an option if other approaches haven’t worked.

Are ganglion cysts related to arthritis?

A ganglion cyst starts when the fluid leaks out of a joint or tendon tunnel and forms a swelling beneath the skin. The cause of the leak is generally unknown, but may be due to trauma or underlying arthritis.
