Primary intraosseous Rosai-Dorfman disease treated with a novel image-guided approach - A case report

Primary intraosseous Rosai–Dorfman disease (RDD) is rare, with limited treatment options. This case report describes a novel image-guided intra-lesional corticosteroid injection for acetabular RDD. The procedure led to significant symptomatic relief and lesion resolution, highlighting a minimally invasive alternative to surgery. Further studies are needed to validate its efficacy.
