Most sciatic tubercle cysts should be distinguished from inflammation of the synovial bursa of the sciatic tuberosity because both painful sites are located at the sciatic tuberosity and are often confused. Sciatic tubercle cysts are often palpable subcutaneous masses in the sciatic tuberosity, which are smooth and easy to push and do not have obvious adhesions with the surrounding tissues. This swelling, if said to be in the later stages, may increase in size due to inflammatory stimulation, and the patient will often feel significant discomfort in this location of the buttocks when sitting or standing, whereas in inflammation of the synovial bursa of the sciatic tubercle, there will be no such subcutaneous swelling when the sciatic tubercle is palpated. Severe inflammation of the synovial bursa of the sciatic tubercle may lead to fluid accumulation in this area, which is often felt as a fluctuating sensation under the hand, and is often accompanied by tingling and vague pain in this area.
