Hombro doloroso: hemangioma en el músculo subescapular

We present a case of a benign vascular tumour, a haemangioma located in the subscapularis muscle as a cause of painful shoulder in a young woman. Such cases have rarely been reported in the literature. A 30-year-old woman was referred to our clinic for a 3-year history of shoulder pain and no significant findings on X-ray and magnetic resonance imaging of the cervical spine and left shoulder. The patient had pain in the left medial scapular area with no palpable mass. Magnetic resonance imaging of the scapula revealed an oval, well-defined, intramuscular vascular tumour compatible with haemangioma of the subscapularis muscle. After excision of the tumour and subsequent rehabilitation treatment, the patient is asymptomatic. Haemangiomas are benign vascular tumours that can cause pain due to swelling in the area of the tumour after prolonged activity. Prognosis is generally favourable.
