Von Hippel-Lindau (VHL) disease is a rare type of oncological disease with an incidence of 1/36,000 individuals in the general population [1,2]. The most frequent tumors are hemangioblastomas (HB) of the central nervous system (CNS) and retina, as well as renal cell carcinoma [3,4]. In addition, pheochromocytomas, pancreatic neuroendocrine tumors, pancreatic serous cystoadenomas, endolymphatic ...
Pancreatic tuberculosis is rare and can occur in the absence of evidence of tuberculosis elsewhere in the body. Here we review the radiological appearance of pancreatic tuberculosis and compare it with other cystic pancreatic lesions, including common lesions (pseudocysts, serous or mucinous cystadenomas, intraductal papillary mucinous neoplasm) and rare lesions such as solid pseudopapillary tu...
Background:Management guidelines for pancreatic intraductal papillary mucinous neoplasms (IPMN) andmucinous cystic neoplasms (MCN) are based on the assumption that mucinous cysts can be accurately distinguished from other pancreatic cystic lesions. Previous studies using surgical material have identified recurrent mutations in GNAS and KRAS in pancreatic mucinous neoplasms. Yet, the diagnostic ...
OBJECTIVE The objectives of this analysis were to define the incidence, natural history, and predictors of neoplasia in pancreatic cysts to determine which patients can safely be observed and which should undergo an operation. SUMMARY BACKGROUND DATA With advancements in imaging technology, cystic lesions of the pancreas are being detected with increased frequency. Many of these lesions are s...
In the context of multiple neuroendocrine tumor syndromes, reproductive abnormalities may occur via a number of different mechanisms, such as hyperprolactinemia, increased GH/IGF-1 levels, hypogonadotropic hypogonadism, hypercortisolism, hyperandrogenism, hyperthyroidism, gonadotropin hypersecretion, as well as, tumorigenesis or functional disturbances in gonads or other reproductive organs. Pr...
Although the exact prevalence of cystic pancreatic lesions is unknown, it is estimated to be around 1% of the general population based on large scale observational imaging studies [1]. While cystic pancreatic lesions are increasingly diagnosed due to the widespread use of cross-sectional imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI), it is not known if th...
The differential diagnosis for cystic lesions of the pancreas is broad and the role of EUS is becoming more clearly defined. Pancreatic cysts may be inflammatory, such as pseudocysts, in which the cyst wall lacks an epithelium. Inflammatory cells line the fluid collection, which may often be located adjacent to an area of acute or chronic pancreatitis. Other types of pancreatic cysts may be bro...
Properly diagnosed benign ovarian formations are a condition for appropriate treatment choice. Qualitative assessment of signs detected by multiparametric ultrasound, including compression elastography, is highly effective in the differential diagnosis formations. Our study became especially relevant women reproductive period since correct influenced choice surgical order to preserve reserve. T...
