Your GP can usually diagnosis a Baker’s cyst by examining your knee and asking about your symptoms.
They will want to know if you have any associated health conditions, such as arthritis.
If your GP cannot diagnose it in this way, they may recommend further tests. These will be used to rule out very rare but more serious conditions, such as a tumour or an aneurysm (a bulge in a section of a blood vessel).
The tests may include:
- an ultrasound – where a scanner that produces high-frequency sound waves is moved over your body to create an image of the inside of your body
- a magnetic resonance imaging (MRI) scan – where you lie inside a large tube and strong magnetic fields and radio waves produce a detailed image of the inside of your body
