Tietze’s Syndrome: A Case Report Tietze syndrome (TS) is a rare inflammatory arthropathy characterized by tenderness, pain, and non-purulent swelling of the costosternal, costochondral and sternoclavicular joints. It often involves the costosternal joints and sternoclavicular jointinvolvement is rare. In this case report, we present a 72-year-old female patient suffering from pain and swelling in the right upper chest wall fo rabout 2 years. Physical examination revealed tenderness in the right sternoclavicular joint and an approximately 2x2 cm moderate swelling. Ultrasonic imaging of the swelling area revealed increased echogenicity and edema in the right sternoclavicular joint area. Laboratory findings were normal. The patient was diagnosed with TS and a local injection of a corticosteroid and local anesthetic mixture was administered. The patient’s complaints decreased significantly after the infiltration. In this case report, we present a TS case with sternoclavicular joint involvement that we treated with local injection. Keywords: Tietze’s syndrome, sternoclavicularjoint, costochondritis
