Background: Maxillary sinus although shows normal anatomical variations and it is important to know about them. Evaluating maxillary sinus and identifying its variations on Computed Tomography not only detects the different variations but also helps in planning and guiding Various Sinus Surgery and preventing possible complications. Purpose: Aim of this study was to detect anatomical variations of maxillary sinuses in patients using Multi-detector Computed Tomography. Materials and Methods: Paranasal sinuses of 130 patients who were subjected to Computerised Tomography of Paranasal Sinus with CT (Seimens 128 slice Somatom Perspective) machine were studied. Results: A total PNS Para Nasal Sinuses of total 130 patients were studied. Out of which only 36 patients had maxillary sinu variations. Among accessory ostia of maxillary sinus was the commonest anatomical variation and was seen in 23 (18%) of cases. Hyperpneumatization of maxillary sinus was detected in 7cases (5%) and Antral septa were found in 13 cases (10%). Conclusion: Thus, it’s important to accurately assess the maxillary sinus on Computed Tomography and to determine the various anatomical variations of the same so as to differentiate pathological lesions from an anatomical variation and avoiding unnecessary surgical explorations and complications.Keywords

Background: Pancreatic neoplasms have highly variable clinical presentation and severity. Computerized Tomography (CT) is the modality of choice for investigating pancreatic neoplasms. Objectives: The objective of our study was to study the CT findings of pancreatic neoplasms in a tertiary care centre. Materials and Methods: CT scan of 20 patients with pancreatic neoplasms were studied after scanning on Siemens Somatom Perspective (128 slice). Results: Majority of the patients i.e., 45% had imaging features of epithelial tumours (Adenocarcinoma). Cystic neoplasms and endocrine tumours were the next most common seen in 30% and 15% of patients respectively. Conclusion: From this study we can infer that pancreatic neoplasms show characteristic findings on CT study & it enables us to assess, grade and stage pancreatic neoplasms with a fair degree of reliability non-invasively. It also helps in designing a management plan for better patient care.Keywords
