Introduction: Patients presenting with a large abdominal mass are to be investigated judiciously and accurate diagnosis is always needed for surgical or medical treatment planning. With newer technological innovations and thinner slice fast imaging by MSCT/MDCT, the confidence level of the radiologist is further improved in diagnosis. Aim: To assess the efficacy of the Computed Tomography in assessing the lesion and to analyze its ability to characterize the lesions by imaging and predict its benign or malignant nature. Materials and Methods: Prospective study of 410 patients subjected to CT with a clinical diagnosis of large intra abdominal mass was done. The study was carried over a period of 18 months at our institute. All data were recorded and analysed.
Results: Out of 26 cases included in our study after applying exclusion criteria, it is observed female [70%] preponderance over men [30%] and ovarian mass lesions 46% and peritoneal/Mesenteric mass lesions[23%] were the leading causes. uterine [7.6%], Gastro intestinal[7.6%], Hepatic [3.8%], Pancreatic [3.8%] and Gall bladder lesions form the rest of our study. CT characteristic features of all encountered lesions were comparable with various previous studies. Conclusion: Though, Conventional ultrasonography is the primary screening tool for patients with a large abdominal mass, for accurate and confident diagnosis, the role of CT in further characterizing the lesion is needed for the clinician for further treatment and it also serves a roadmap if surgery is contemplated.
