Abstract Introduction: Scapular osteochondromas represent 3% to 4% of all osteochondromas. Although many cases of osteochondromas affecting the body of the scapula have been reported in the first three decades of life, case reports of osteochondroma affecting the coracoid process or the glenoid of the scapula are limited. Patient concerns: We report a case of a 56-year-old male with progressive pain and swelling of the left shoulder for six months. Diagnoses: The diagnosis was dual osteochondromas arising from the coracoid process and the glenoid of the left scapula. Interventions: Complete excision was performed. Outcomes: The patient was discharged without any complications after 10 days of postoperative wound care. His symptoms relieved at three months after surgery. At the last follow-up (two years postoperatively), the patient remained in good condition. He had full range of motion of the shoulder without any signs of recurrence. Conclusion: Dual osteochondromas arising from the glenoid and the coracoid process can cause severe dysfunction with coracoid impingement syndrome of the ipsilateral shoulder. In older individuals, it is necessary to differentiate osteochondroma from a malignant tumor.
