Ultrasound-guided aspiration and steroid injection of a posterior cruciate ligament ganglion cyst: report of a case.
Ganglion cysts are benign masses that originate from mucinous degeneration of the connective tissues and are quite rare when arising from the knee joint. Symptoms are often represented by pain, joint tenderness, effusion and occasional swelling with a palpable mass in the popliteal region of the knee. Percutaneous aspiration followed by a corticosteroid injection of a ganglion cyst has either a diagnostic or therapeutic meaning and its guidance through ultrasound allows the operator to make more accurate the procedure, ensuring the correct placement of the needle inside the lesion. We report our experience in the treatment of a voluminous ganglion cyst of the posterior cruciate ligament performed through the ultrasound guidance in a symptomatic young patient.
