Evaluation of proptosis by computed tomography

ABSTRACT

Computed tomography [CT] was done for 30 patients complaining from proptosis whether unilateral or bilateral to assess its reliability in differentiating its causes and extent. Other radiological methods, histopathology and surgery were used for confirmation in addition to the clinical data. Three groups of retrobulbar, paraorbital and global lesions were defined. The CT was found to be an essential diagnostic tool for the detection of the global and orbital lesions, while it had to be combined with plain x-ray in dealing with parorbital lesions
