ABSTRACT
The objective of the study was to evaluate the effectiveness of diagnosis of the intraorbital tumours with the help of CT scan. This cross sectional study took place in the Department of Radiology and Imaging, Dhaka Medical College Hospital and Department of Radiology and Imaging, National Institute of Ophthalmology during the period of January 2017 to December 2018. The sampling technique was purposive and sample size was 67. Patients attending outdoor and indoor patient facilities of the Department of Ophthalmology of the aforementioned Institute and Hospital and referred to their respective Radiology and Imaging Departments with suspicion of intraorbital tumours were included in the study. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CT scan in the diagnosis of the intraorbital tumours were determined. Out of 67 cases, 31 (46.3%), 14 (20.9%), and 22 (32.8%) patients were diagnosed respectively with malignant tumour, benign tumour, and nontumorous lesions on histopathology. On the other hand, out of 67 cases 37 (55.22%), 16 (23.88%), and 14 (20.9%) patients were diagnosed with malignant tumour, benign tumour, and nontumorous lesions respectively with the help of CT scanning procedures. The accuracy of CT scan was 85.07% with sensitivity of 93.54%, specificity of 77.77%, and predictive value of 78.38% (positive) and 93.33% (negative) for findings of the malignant intraorbital tumours. In the case of radiological findings for benign intraorbital tumours, the accuracy of CT scan was 97.01% with sensitivity of 100%, specificity of 96.23%, where predictive value was 87.50% positive and 100% negative. From the result of this study, it may be concluded that CT scan is a useful modality to correctly identify patients with a disease and without a disease of intraorbital tumours. In case of benign tumours the validity tests showed relatively more accuracy.
