Role of Multidetector Computed Tomography Scan in Evaluation of Neck Mass
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 5, Issue 11
Abstract
Introduction: Neck masses are frequently encountered in general population and hospitals. It is important to differentiate a malignant neck lesion from a benign lesion. Early and precise diagnosis helps in choosing the line of management. Aims and Objectives: To determine sensitivity and specificity of multidetector computed tomography (MDCT) scan in the differentiation of benign and malignant neck mass in comparison with histopathological diagnosis. Materials and Methods: Hospital based observational prospective cross-sectional study was conducted in the Department of Radio diagnosis, Pt. JNM Medical College Raipur, and associated Dr. BR Ambedkar Hospital Raipur (C.G.) from January 2016 to September 2017 on 60 patients of all age who presented with neck mass. Contrast-enhanced scans using non-ionic contrast media (60–80 ml at the rate of 3 ml/s) were performed spirally. Result: In our study, 60 patients of neck masses were included. MDCT was diagnosed 31 (51.7%) patient of neck mass as benign neck mass and 29 (48.3%) patient of neck mass as malignant, however, on histopathology 29 (48.3%) patient of neck mass were diagnosed as a benign and 31 (51.7%) patient of neck mass were diagnosed as a malignant. Sensitivity, specificity, positive predictive value, and negative predictive value of MDCT scan to differentiation between benign and malignant neck mass in comparison with histopathology was 90.32%, 96.55%, 96.55%, and 90.32%, respectively. Significant association was note between two diagnoses (P < 0.0001). Conclusion: MDCT had high sensitivity and specificity in differentiation of benign versus malignant neck mass lesion which helps in the further planning of management of these lesions but requires histopathology for better management.
