Validity of CT-Scan for the detection of malignant orbital mass among pediatric patients.

Abstract

Background: The validity of CT-Scan for detection of orbital mass among pediatric patients is very important noninvasive radiological modality. Objective: The purpose of the study was to find out the validity of CT-Scan to detection of orbital mass among pediatric patients with a view to develop it as an important radiological modality for the detection of orbital mass. Methodology: This is a cross sectional study was carried out in Ophthalmology and Radiology and Imaging department of National Institute of Ophthalmology (NIO) from January 2012 to December 2013. All the patient below 18 years of age presented with suspected orbital mass at Ophthalmology and Radiology and Imaging department of NIO and performed CT- Scan of orbit for diagnosis of the disease and also done histopathology after operation was enrolled in this study. Result: A total number of 70 patients clinically suspected cases orbital mass lesion who came in department of ophthalmology and Radiology and Imaging of National institute of ophthalmology (NIO), Dhaka, during the period of January 2012 to December 2013, were included in this study. In this present study it was observed that sensitivity 96.4%, specificity 95.2%, accuracy 95.7%, positive predictive values 93.1% and negative predictive values 97.6% of the CT scan evaluation for orbital mass lesion in pediatric population. Conclusion: The validity of CT-Scan for detection of orbital mass among pediatric patients is very important, it is noninvasive useful method in the differentiation between benign and malignant orbital mass.
