The coracoclavicular joint is a diarthrodial synovial joint that is eventually located between the upper surface of the horizontal part of the coracoid process and the conoid tubercle of the clavicle, and is considered an unusual anatomical alteration. The coracoclavicular joint has a low prevalence and can be diagnosed by imaging tests - radiography and computed tomography. Treatment can be performed both conservatively and surgically. We report a case of an 81-year-old female patient presenting of pain in her left shoulder due to coracoclavicular joint arthrosis. A radiograph of the left shoulder was performed, which detected a deformity in the lower portion of the middle third of the clavicle and the upper portion of the coracoid process, corresponding to the coracoclavicular joint, a finding confirmed by computed tomography. The patient was treated conservatively with analgesics (Dipyrone) and anti-inflammatories (Ibuprofen) with improvement in symptoms.
