INTRODUCTION A neck mass can be frequently seen in clinical practice. The close proximity of various structures in the neck creates a diagnostic problem. The precise anatomical location and imaging appearances are important for accurate diagnosis and formulating the differential diagnoses of neck masses. The present study was undertaken to evaluate diagnostic efficacy of ultrasonography and computed tomography in neck masses. AIM To assess the efficacy of Ultrasonography and Computed Tomography in the evaluation of neck masses. MATERIAL AND METHODS This study was conducted in the department of E.N.T. in co-ordination with the department of Radiodiagnosis, Oncology and Pathology at LLR & Associated Hospital, GSVM, Medical College, Kanpur.Total number of patients included were 50. RESULT Of the 50 patients of age group 3-70 years who presented with neck masses, majority of patients belonged to 20-30 years of age group (10 patients , 20% ) with male dominance 62% ( 31 out of 50 patients).Maximum number of neck swelling were of lymph node origin14(28%). Out of those lymph nodes maximum were malignant. Out of the non nodal masses 36(72%), maximum were benign. CONCLUSION High resolution sonography and color Doppler is a useful modality for diagnostic evaluation of neck masses in every age group. It is simple, noninvasive and inexpensive diagnostic tool. CT ensures accurate anatomical localization and lesion characterization in benign lesions. In malignant tumors, it is useful for staging and provides essential information about the tumor extent that directly affects the surgical approach necessary for curative resection.
