Journal Title: IJSR-International Journal Of Scientific Research - Year 2019, Vol 8, Issue 7
Abstract
BACKGROUND: Before advent of cross section imaging radiologists were of limited help in diagnosis of neck lesions, especially those involving deep neck spaces of suprahyoid neck (SHN). AIM: Aim of our study is to characterise neck lesion by its morphological characteristics and enhancement pattern, outlining the extent, assessment of lymphadenopathy, look for criteria for operability and histopathological confirmation. METHODS & MATERIALS: In this study 100 cases of neck masses were evaluated retrospectively in our department. The CT scan was performed prior to the treatment in all these patients. CT imaging feature includes location, size/diameter, degree & pattern of enhancement, intraluminal/exophytic, internal necrosis & hemorrhage, local spread, nodal & distant metastasis. RESULTS: Out of 100 patients studied 27% were benign and 73% were malignant neck lesions, overall there was a male preponderance with a male to female ratio of 2.1:1. Benign lesion were common in the age group of 16-45 yrs. while malignant lesions were more common in the elderly age group of >45 years. Most of the benign (26%) and malignant lesions (81%) showed heterogeneous enhancement pattern. Bone invasion seen in 15% benign lesions, 19% of malignant lesions and cartilage invasion seen in 7% of malignant lesions. On correlation with HPE, among malignant lesions most common was Squamous cell carcinoma (48%) and among benign lesions most common was nonspecific inflammation. The sensitivity and specificity of study is 95.7% & 77.5% respectively, with positive predictive value and negative predictive value of 90.4% & 88.9% respectively and Accuracy is 90%.
