Intrapancreatic hypervascular lesions may represent metastases, neuroendocrine tumors, or intrapancreatic accessory spleens. The benign intrapancreatic accessory spleen can be difficult to separate from a malignant neuroendocrine tumor or metastasis. We report three cases of pancreatic lesions that underwent pancreatic surgery due to suspicion of malignancy on imaging; all cases were histologically intrapancreatic accessory spleens. Our cases point to the importance of performing single-photon emission computed tomography with heat-damaged Tc-99m-pertechnetate labelled erythrocytes to identify splenic tissue, even though small lesions can show a false-negative result.

Mimics of pancreatic neoplasms at cross-sectional imaging: Pearls for characterization and diagnostic work-up.

Interpreting imaging examinations of the pancreas can be a challenge. Several different entities can mimic or mask pancreatic neoplasms, including normal anatomic variants, non-pancreatic lesions, and both acute and chronic pancreatitis. It is important to distinguish these entities from pancreatic neoplasms, as the management and prognosis of a pancreatic neoplasm, particularly adenocarcinoma, have considerable impact on patients.

Epidermoid cyst in intrapancreatic accessory spleen (ECIPAS) is a rare benign condition that occasionally mimic malignant pancreatic neoplasms. We present a case of ECIPAS in a 53-year-old asymptomatic male, initially discovered incidentally during imaging for a suspected hepatic hemangioma. The lesion, located in the pancreatic tail, demonstrated characteristic imaging features on contrast-enhanced computed tomography and superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance imaging (MRI), including a cystic component with peripheral solid tissue exhibiting splenic enhancement patterns.

Article Synopsis
  • The increase in pancreatic cystic lesions (PCLs), especially intraductal papillary neoplasms (IPMNs), is largely due to more advanced imaging techniques like CT and MRI, leading to frequent incidental findings.
  • Surveillance for IPMNs is crucial because of their cancer risk, but their similar appearance to benign lesions can cause diagnostic errors, which may result in unnecessary treatments and strain on healthcare resources.
  • The paper focuses on differentiating IPMNs from similar lesions (like serous cystadenomas and others) by examining their imaging features and characteristics, aiming to improve diagnosis accuracy and patient care while reducing healthcare burdens.

β-cell dedifferentiation in HOMA-βlow and HOMA-βhigh subjects.

J Clin Endocrinol Metab

Department of Endocrine and Metabolic Diseases, Shanghai Institute of Endocrine and Metabolic Diseases, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Context: β-cell dedifferentiation ratio is increased in type 2 diabetes; but its direct link to in vivo β-cell function in human remains unclear.

Objective: The present study was designed to investigate whether β-cell dedifferentiation in situ was closely associated with β-cell function in vivo and to identify targets crucial for β-cell dedifferentiation/function in human.

Methods: We acquired HOMA-β values, calculated the number of hormone-negative endocrine cells and evaluated important markers and novel candidates for β-cell dedifferentiation/function on paraneoplastic pancreatic tissues from 13 patients with benign pancreatic cystic neoplasm (PCN) or intrapancreatic accessory spleen.
