Abstract

Until computer tomography (CT) was devel-oped, we could not observe an intraorbital structure. Because the adipose tissues in the orbit become very effective negative contrast media on CT, most lesions can be found very easily. Orbitsare in contact with paranasal sinuses and intrac-ranial structure, and therefore some lesions at these areas often extend to orbits. Most of these lesions can be also found easily with CT.

The diagnosis by CT is based on the changes of absorption value and the deviation and de-formity in normal structures, then most lesions due to different causes show the same findings.
