Abstract:
:The orbital lesions in six patients with Wegener's granulomatosis were studied by computer assisted tomography (CAT). Four patients had active orbital disease and proptosis, and each was found to have orbital masses accompanied by varying degrees of bone and sinus destruction. Two additional patients with histories of proptosis had no orbital lesions at the time of CAT study.
