Clinical Characteristics and Image Manifestations of a Rare Retinoblastoma with a Bone Metastasis.

The simultaneous involvement of the bone marrow and cortex is characteristic manifestations in images of RB with bone metastases. Multidisciplinary treatment especially intravenous chemotherapy is useful, at least at the beginning.
