Ganglion Cyst Diagnosis
Ganglion cyst diagnosis is usually based on the location of the lump and its appearance. They are usually oval or round and may be soft or very firm. Ganglion cysts at the base of the finger on the palm side are typically very firm, pea sized nodules that are tender to applied pressure, such as when gripping. Light will often pass through these lumps, (transillumination) and this can assist in the diagnosis. Your physician may request x-rays in order to investigate problems in adjacent joints. Ganglion cysts at the end joint of the finger frequently have an arthritic bone spur associated with them.
