COMPUTED TOMOGRAPHIC IMAGING OF PEDIATRIC ORBITS
Abstract
From January 1995 to December 1996, computed tomographic imaging of the orbits was performed on 48 pediatric patients at the Department of Radiology, Faculty of Medicine, Chiang Mai University. Pathological and/or clinical proofs of diagnoses were successfully obtained from only 35 of these patients, in whom ocular (n=21) and orbital (n=14) diseases were found. These ocular diseases included retinoblastoma (n=14) and non-tumoral retinal detachment (n=3); the remainder were persistent hypertrophic primary vitreous, congenital glaucoma, intraocular foreign body, and posttraumatic lens aspiration. The orbital diseases included acute myeloblastic leukemia (n=3), preseptal cellulitis (n=3), neurofibroma (n=2); the remainder were neuroblastoma, primitive neuroectodermal tumor, rhabdomyosarcoma, capillary hemangioma, orbital cellulitis, and optic neuritis. The computed tomographic findings of these patients are reviewed and discussed.
