Diagnosis | Ganglion

Diagnosis

Often the doctor can diagnose a ganglion by palpation after asking the patient about his symptoms and medical history (anamnesis). If other causes for the swelling are possible, the diagnosis can be confirmed by an ultrasound examination. The ultrasound can also reveal possible arthrosis or injuries as a trigger for the ganglion.

If, on the other hand, there is a suspicion that a real tumor may be present, a tissue sample (biopsy) is usually taken. Prior to surgical removal of the ganglion, an MRI of the respective region (e.g. hand, knee, foot, etc.) may be performed to determine the exact location and extent.

The basic diagnostics for a ganglion are a physical examination and an ultrasound examination. An X-ray may also be performed to detect joint damage caused by the ganglion. An MRI (magnetic resonance imaging) is not a standard imaging procedure for ganglions, as most ganglions are clearly visible from the outside and are easily palpable. An MRI is basically only required if the treating physician suspects further joint damage or if the ganglion is very small and located in the joint.

Frequency

A ganglion usually occurs between the ages of 20 and 40, but it can also occur in children. Women are affected about twice as often as men. The most common site of ganglion is on the wrist, preferably on the outside of the hand on the back of the hand.

Somewhat less frequently, ganglia are found on the flexion side of the hand in the area of the thumb saddle joint or on the finger joints. In rare cases, a ganglion also occurs on the back of the foot or knee.
