UNLABELLED Imaging appearance of cyst-like changes is most frequently described in primary neuroendocrine lesions, especially pancreatic NETs.The imaging finding of a pseudocystic lesion of the liver puts in differential diagnosis many pathologies such as infectious diseases, simple biliary cysts up to biliary cystadenomas and eventually to primary or metastatic malignancies.Primary or metastat...

pancreatic neuroendocrine tumors (pnet) are uncommon pancreatic neoplasms, accounting for 1-2% of all pancreatic tumors. however, they have a better prognosis and long-term survival compared to exocrine pancreatic cancer. pnets can be divided into functional or non-functional based upon whether or not they excrete active substances relevant to specific clinical syndromes. skeletal muscle metast...

A 67-year-old woman was admitted to our hospital under suspicion of a hepatic tumor, which had been previously diagnosed to be an adenocarcinoma by fine needle aspiration. Computed tomography and magnetic resonance imaging revealed a large tumor measuring 9 cm in diameter in Couinaud's hepatic segments 4, 5, and 8. We diagnosed the patient to have primary liver cancer, and suspected intrahepati...

Introduction: Neuroendocrine tumors(NET) represent rare neoplasms with majority primary NETs being gastroenteropancreatic or bronchopulmonary origin. A hepatic NET is most likely a metastastic lesion. Cystic lesions are commonly either infectious, benign cystic lesions, if malignant; cystadenocarcinoma, hepatocellular carcinoma, metastasis degeneration. Primary neuroendocrine tumors(PHNETs) and...
