Snapping Scapula Syndrome in the Setting of Elastofibroma Dorsi: A Case Report

A 54-year-old woman presented with a 15-year history of progressively worsening left snapping scapula syndrome (SSS) in the setting of ipsilateral elastofibroma dorsi. Her pain was refractory to multiple conservative measures. She was successfully treated with focal ultrasound-guided corticosteroid injection to the superomedial border of the scapula. There was demonstrable improvement in findings between pre- and post-procedural MRI examinations. Despite the underlying cause of SSS, trials of nonoperative treatment techniques are warranted before considering surgical options. Focal ultrasound-guided corticosteroid injection, in conjunction with physiotherapy, is one such example.
