Abstract :

Objective: To evaluate the role of MDCT and MRI in neck masses for characterization based on location, extent, morphological characteristics , enhancement pattern andOutlining the extent in terms of involvement of adjacent structures, vessels and possible lymphadenopathy. Methods: A prospective observational study on MDCT and MRI of 40 patients with complaint of neck swelling was carried out for a period of 1 year (October 2017 to September 2018) in Radiology department of Geetanjali Medical College and Hospital .The data were collected , evaluated for the role of CT and MRI in different neck masses and outlining their extent .The follow up diagnosis was established on the basis of operative and histopathologic findings wherever possible. Result and Conclusion: In our study, 67.5% of patients were males and 32.5% were females. Out of 40 cases, 15 cases showed benign lesions and 25, showed malignant lesions. Males being affected more with both benign and malignant lesions. Tubercular lymphadenitis being most commonest benign cause had sensitivity and specificity of 85% and 93% on CT and 93% and 95% on MRI, with diagnostic accuracy being 92% and 94% on CT and MRI respectively. Other benign lesions like abscess, ranula etc having 100% diagnostic accuracy on CT and MRI. Primary carcinomas having almost 68% and 88% of diagnostic accuracy on CT and MRI, with metastatic lymphadenopathy having 92% and 94% of diagnostic accuracy on CT and MRI respectively.
