Role of Computed Tomography in evaluation of Proptosis
Keywords:Computed Tomography, proptosis, inflamation
Background: To analyze the role of Computed Tomography in the evaluation of proptosis.
Methods: It is a retrospective review of 30 patients with the history of proptosis who were referred to the department of radiology and imaging for computed tomography of orbit. Computed tomography of orbits was evaluated to assess the nature and extension of the lesion. Final diagnosis was made based on the histopathology, operative findings and clinical outcome. Statistical analysis was carried out with the help of SPSS - 17 to find the accuracy of Computed Tomography.
Results: Thirty patients ranging from three to 73 years were included in the study. Mean age was 35.4±19.6 years. Male:Female ratio was 2:1. Most common cause of proptosis was inflammation (47%) followed by tumor. Among the inflammatory causes pseudotumor was the most common type. Other causes of proptosis include tumor (37%), Vascular (10%), Infection (3%) and Trauma (3%). Accuracy of Computed Tomography in the diagnosis of etiology of proptosis was 86.6%.
Conclusion: Computed tomography is the simple, cost effective technique in the evaluation of proptosis with the accuracy of 86.6%. Inflammation was the most common cause of proptosis.
