Symptoms Of A Baker's Cyst
Your doctor will examine your knee and feel the swelling. If the cyst is small, he or she may compare the affected knee to the healthy one and check your range of motion. By shining a light through the cyst, your doctor can tell if there is fluid inside the swelling.
If the cyst rapidly increases in size or causes severe pain or fever, your doctor may recommend more tests. These will determine if some other form of growth, such as a tumor, is causing the swelling. These non-invasive tests include MRIs and ultrasounds.
Although a cyst will not show up on an x-ray, one might be used as well to check for other problems, such as inflammation or arthritis.

A blood clot can also cause bruising and swelling behind the knee and on the back of the calf. It is important that your doctor examines the swelling to determine if the cause is a cyst or a clot.
