Clinical and CT histological diagnosis of orbital tumors

Abstract

The clinical manifestation and characteristics of CT image of 117 cases of orbital tumors in our hospital were investigated. The hemangioma had the highest incidence, and the less common tumors were, in sequence of incidence, pseudotumor, dermoid cysts, neurilemraoma, polymorphous adenoma and meningioma. The sensitivity in diagnosis of orbital tumor by CT was 93.3 %. The coincidence of CT histological diagnosis with pathology were 83.3 %, 82.6 % and 71.4 % for dermoid cysts, hemangioma, and pseudotumor respectively, but the general coincidence of CT histological diagnosis with pathology was only 67.8 %. When CT was combined with ultrasound, cytological examination and clinical manifestations, the accuracy of histological diagnosis could be improved to 83.3 %.
