We report a case of Langerhans cell histiocytosis (LCH) involving the right scapula in a 4-year-old child. Because of progressive shoulder pain and immobility methylprednisolone was injected directly into the lesion under computed tomography (CT) guidance. Follow-up studies with magnetic resonance imaging (MRI) and ultrasound (US) revealed continuous ossification of the osteolytic lesion with healing after 6 months. Plain films and CT confirmed the healing process. We consider intralesional corticoid instillation a safe method when performed under CT guidance. For initial evaluation and follow-up, MRI and US yielded reliable results in comparison to plain films and CT, thus helping to reduce the radiation dosage in children.
