Radiology of orbital masses in children.

Ninety-three children (103 orbital tumours) have been examined. Typical appearances were noted in one half of the cases. Most of the optic nerve gliomas, rhabdomyosarcomas, metastatic neuroblastomas and all the dermoids were typical. The most variable appearance was seen in vascular malformations which sometimes could be confused with typical lesions of other histologic type.
