Neuroradiology of Ocular and Orbital Tumors

Abstract

This chapter on neuroradiology for ophthalmologic tumors discusses the basic utilization of computed tomography and magnetic resonance imaging in the evaluation of lesions involving the globe and orbit. The protocol for these techniques, relevant imaging anatomy, and imaging features of the more common ophthalmologic tumors are discussed. The common radiographic features of ocular lesions, such as retinoblastoma, melanoma, and uveal metastases, as well as orbital lesions, including lymphoma, rhabdomysarcoma, nerve sheath tumors, fibrous lesions, and orbital pseudotumors are discussed. Lesions of the optic nerve, including glioma and meningioma, are also covered. The final section discusses radiographic findings for lesions of the lacrimal gland, secondary spread of tumors to the orbit and periocular region, and cutaneous lesions of the periocular region, including perineural tumor spread.
