Purpose or Case Report: Radiology plays a crucial role in the detection, diagnosis, and longitudinal surveillance of tumors and their mimics in the pediatric orbit. Familiarity with the imaging spectrum of orbital pathology is necessary for making an accurate assessment to guide treatment, referrals, and in some cases further workup such as genetic testing. This exhibit will highlight the key imaging features of benign and malignant masses in the pediatric orbit, many of which are unique to this age group. Retinoblastoma, medulloepithelioma, optic pathway glioma, rhabdomyosarcoma, and plexiform neurofibroma will be amongst the neoplasms presented. Non-neoplastic lesions including lymphatic and vascular malformations, dermoid cysts, and congenital orbital fibrosis will be reviewed. Lesions of the bony orbit with intra-orbital extension will also be presented, including Langerhans cell histiocytosis, fibrous dysplasia, and neuroblastoma metastasis. Each type of pathology will be illustrated by representative case(s) from our institution.
