Abstract

Rationale:

The scapula is relatively rare site for osteochondroma. Scapula osteochondroma is usually asymptomatic, however it may present with features such as pseudowinging, snapping scapula, bursa formation, chronic pain, and cosmetic deformities. To our best knowledge, this is the first report in the English literature about osteochondroma of ventral scapula associated with chest pain due to rib cage compression.

Patient concerns:

A 14-year-old boy was transferred to the orthopedic clinic from thoracic surgery department with a complaint of intermittent, dull, and diffuse aching pain around left chest wall and back from the past 2 months. The patient was previously diagnosed with multiple osteochondromas on another side; proximal tibia and distal femur.

Diagnosis:

A radiopaque mass like lesion was observed on the scapula in the posteroanterior view of the chest, and compression of chest wall was also seen. In chest computed tomography (CT), pedunculated outgrowing bony mass was noted in the anterior aspect of the left scapular wing, which showed the continuity of bony cortex and medulla. This bony mass showed the mass effect on the left chest wall, causing left thoracic cavity deformity by making it narrower than the right

Interventions:

Surgery was performed under general anesthesia. After the surgery, the arm was immobilized by putting it in an abductor pillow brace for 3 weeks, and during that period pendulum exercise was permitted.

Outcomes:

The patient's symptoms resolved in the immediate postoperative period. At 1 year's follow-up, the patient was symptom free and there was no evidence of recurrence of the tumor.

Lessons:

We recommend that in case of patients who have a history of osteochondroma and complaint of chest pain, surgeons should become suspicious of the presence of osteochondroma of the ventral scapula. In this situation, we recommend chest radiography, pulmonary function test, and chest CT for early detection and treatment.
