case_images: X rays of the right shoulder showed: osteopenia, an irregular thickened white line at the upper humeral metaphysis, a zone of rarefaction under the same metaphysis and a periosteal reaction (Fig. 1).
case_images: The sagittal ultrasound image shows heterogeneous hypoechoic lesions compatible with subperiosteal abscess (red arrow).
