This presentation demonstrates the advantages of a fourth generation CT scanner in prognosis and localization of orbital space taking lesions, including its use as a localization guide for fine needle aspiration biopsy. It also provides an accurate means of follow-up of orbital lesions which have been either left in situ, partially excised, or excised. Six patients with difficult orbital problems of various types have been described to demonstrate how this high resolution CT scanner was utilized to improve the recognition and management of these problems.
