Accurate diagnosis of metastases is of the utmost importance for treatment planning, for children with metastatic neuroblastomas and chloromas in the orbit often present initially with orbital manifestations. All fourteen patients appeared a soft tissue mass with lytic bone destruction. Postcontrast T1W images with fat suppression demonstrated extensive high signal intensity within the bone marrow of bilateral lateral orbital walls and greater wings of the sphenoid bone as well as bilateral petrous apices, which were the specific findings different from those of other lesions including the Langerhans cell histiocytosis and the rhabdomyosarcoma.
