In this review, we will focus on rare pancreatic tumors. Most of these tumors do not have distinct characteristic appearances so the key to diagnosis requires a combination of imaging appearance, laboratory data, patient demographics, and associated medical syndromes in order to narrow the differential diagnosis. Nonetheless, imaging plays a vital role

Incidental, nonfunctional pancreatic endocrine tumors (PET) are observed with increasing frequency. Most are insulinomas. Endoscopic ultrasound with fine-needle aspiration plays a significant role in the localization and tissue diagnosis of PET. Establishing PET behavior as aggressive or indolent remains challenging especially preoperatively.

The goal of this article is to describe the different types of benign pancreatic neoplasms, methods to distinguish between them, and treatment options. Pancreatic adenocarcinoma is associated with specific neoplastic lesions that are similar in radiographic appearance to some benign lesions.

Pancreatic Tumor Microenvironment
2020The pancreatic ductal adenocarcinoma (PDAC) microenvironment is a diverse and complex milieu of immune, stromal, and tumor cells and is characterized by a dense stroma, which mediates the interaction between the tumor and the immune system within the tumor microenvironment (TME).

Pancreatic neuroendocrine tumors
Indian Journal of Gastroenterology, 2012Pancreatic neuroendocrine tumors (pancreatic NETs) are rare, low- to intermediate-grade neoplasms thought to arise from the pancreatic islets. Recent advances in pathology and our understanding of the biological behavior of this group of tumors has resulted in changes in their nomenclature and how we treat them.

Pancreatic endocrine tumors have been steadily growing in incidence and prevalence during the last two decades, showing an incidence of 4-5/1,000,000 population. They represent a heterogeneous group with very varying tumor biology and prognosis. About half of the patients present clinical symptoms and syndromes related to substances released from the ...

Pancreatic neuroendocrine tumors
Current Opinion in Gastroenterology, 2019Pancreatic neuroendocrine tumors (pNETs) are a rare, heterogeneous group of pancreatic neoplasms with a wide range of malignant potential. They may manifest as noninfiltrative, slow-growing tumors, locally invasive masses, or even swiftly metastasizing cancers.In recent years, because of the increasing amount of scientific literature available for ...

Imaging plays a key role in the diagnosis and staging of pancreatic tumors. Imaging modalities utilized for the evaluation of pancreatic tumors include: transabdominal and endoscopic ultrasound, computed tomography, and magnetic resonance imaging. Each of these modalities has different strengths and weaknesses which must be considered in the setting of

MRI employing current imaging techniques is able to detect various pancreatic tumors well, and is able to stage and characterize tumors accurately. This review article describes various current MR techniques emphasizing breath hold spoiled gradient echo (SGE) imaging, fat suppression, dynamic gadolinium administration and MR cholangiographic techniques.
