Department of Radiology, University of Alabama Medical Center, University of Alabama at Birmingham, 619 19th St South, JT N 331, Birmingham, AL 35249.Radiology (Impact Factor: 6.87). 01/2013; 266(1):28-36. DOI: 10.1148/radiol.12112469
In this review, a brief discussion of the important events of pancreatic embryology is followed by presentation of congenital anomalies and normal variants. For each variant, the appearance at different radiologic modalities including computed tomography, magnetic resonance (MR) imaging, endoscopic retrograde cholangiopancreatography, MR cholangiopancreatography, and fluoroscopy will be demonstrated. © RSNA, 2013.

ABSTRACT: Purpose To investigate the computed tomography (CT) features of heterotopic pancreas of the jejunum (HPJ) and to assess their associations with HPJ pathology features. Methods In this retrospective series analysis, two radiologists reviewed the CT images of 17 patients with surgically proven HPJ in order to determine in consensus the location, long diameter, margin, shape, contour, and growth pattern of the lesions, the presence of a duct-like structure, the lesion enhancement patterns, including the homogeneity, and the degree of contrast enhancement compared with that of the main pancreas. The pathology features of the surgical specimens were reviewed and their associations with the CT features were assessed. Results On CT, the HPJs typically appeared as a small (Abdominal Imaging 06/2014; 40(1). DOI:10.1007/s00261-014-0177-y · 1.63 Impact Factor

ABSTRACT: The early and accurate characterization of pancreatic masses remains a challenge in diagnostic radiology, while the continuously evolving diagnostic possibilities give rise to an ever-increasing number of incidentally found pancreatic masses. This article discusses the relevance and role of ultrasound, endoscopic ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) in the diagnosis of pancreatic lesions. Specific protocols such as MR cholangiopancreatography and multiphase CT allow for a close characterization. While CT and MRI deliver information to further evaluate pancreatic disease, PET/CT has shown potential for staging purposes and in the clinical follow-up of pancreatic cancer patients. Common differential diagnoses regarding pancreatic cancer are discussed, and typical imaging features of anatomical variations, cystic lesions and pancreatitis are illustrated, together with clinical signs of pancreatic disease. The use of cross-sectional imaging in correlation with clinical features allows for an accurate and early detection of pancreatic masses and assists in differentiating benign from malignant disease. © 2014 S.
