Ken Kamata, Masayuki Kitano
Endoscopic methods are increasingly used in the diagnosis of cystic lesions of the pancreas. The two major endoscopic approaches are endoscopic ultrasonography (EUS) and trans-papillary diagnosis. EUS-guided fine needle aspiration cytology and EUS-guided fine needle-based confocal laser endomicroscopy have been employed in the differential diagnosis of mucinous and non-mucinous pancreatic cysts. EUS is the most sensitive modality for detecting mural nodules (MNs) in IPMNs. Contrast-enhanced harmonic EUS (CH-EUS), as an add-on to EUS, is useful for identifying and characterizing MNs...

Choledochal cysts rarely present with acute pancreatitis. We report a patient with type I choledochal cyst(s) who had concomitant acute frank hemorrhagic pancreatitis. A 14-year-old male noted with a history of recurrent abdominal pain, fever and jaundice. Ultrasonography (US) of abdomen at the Emergency Department depicted distended gall bladder with wall thickening. Apparently dilated intrahepatic ducts (IHDs) and fusiform dilatation of the common bile duct (CBD), and mild dilatation of the pancreatic duct were also noted, suggesting a type I choledochal cyst( )...

BACKGROUND: Medullary carcinoma of the pancreas (MCP) is a rare malignant pancreatic tumor. The World Health Organization classification defines the tumor as a subtype of pancreatic ductal carcinomas. MCP is histologically characterized as having highly pleomorphic cells with syncytial morphology, expansive tumor growth, and necrosis. The pathogenesis and clinical course of MCP are largely unknown. Herein, we report an unusual case of MCP that was radiologically followed up for 9 years prior to surgical intervention...

Obesity, insulin resistance, and metabolic syndrome continue to increase in prevalence. Hypertriglyceridemia is commonly associated and represents a valuable marker of metabolic syndrome. An increase in subcutaneous fat deposition places patients at risk for visceral adipose deposition in sites such as the liver, heart, and pancreas. Pancreatic steatosis in the setting of metabolic syndrome is a rapidly emerging entity whose clinical spectrum remains to be defined. Hypertriglyceridemia is an accepted cause of acute pancreatitis but its role in chronic pancreatic injury remains to be explored...

BACKGROUND: Pancreatic cancer has a very poor prognosis as most patients are diagnosed at an advanced stage when curative treatments are not possible. Breath volatile organic compounds (VOCs) have shown potential as novel biomarkers to detect cancer. The aim of the study was to quantify differences in exhaled breath VOCs of patients with pancreatic cancers compared with cohorts without cancer. METHODS: Patients were recruited to an initial development cohort and a second validation cohort...

A 1-y-old spayed female ferret (Mustela putorius furo) was referred for additional diagnostic evaluation after physical examination by the referring veterinarian revealed a cranial abdominal mass. The ferret had a 2-wk history of inappetence, weight loss, and lethargy. On presentation, the ferret was thin, and an approximately 3-cm mass was palpable in the cranial abdomen. No other abnormalities were noted. Abdominal ultrasonography confirmed the presence of a soft-tissue structure, with a moderate blood supply and mesenteric lymphadenopathy...

BACKGROUND: Anaplastic carcinoma of the pancreas is a rare pancreatic neoplasm with a poor prognosis. It is classified as a variant of ductal adenocarcinoma, but the clinical features and treatment of it remain unknown because of its rarity and aggressiveness. Endoscopic ultrasonography and endoscopic ultrasound-guided fine-needle aspiration are useful techniques for the diagnosis of pancreatic tumors with high sensitivity and specificity. CASE PRESENTATION: A 72-year-old Japanese woman presented with a diagnosis of acute pancreatitis, and a cystic lesion with slightly high density area was observed by computed tomography in her pancreatic head...

BACKGROUND: Perfusion assessment of the pancreas is challenging and poorly evaluated. Pancreatic affection is a prevalent feature of cystic fibrosis (CF). Little is known about pancreatic perfusion in CF. We aimed to assess pancreatic perfusion by contrast-enhanced ultrasound (CEUS) analysed in the bolus-and-burst model and software. METHODS: We performed contrast enhanced ultrasound of the pancreas in 25 CF patients and 20 healthy controls. Perfusion data was analysed using a dedicated perfusion model providing the mean capillary transit-time (MTT), blood flow (BF) and blood-volume (BV)...

Solid serous cystadenoma of the pancreas is the rarest subtype of serous cystadenoma. Cystic structures are difficult to recognize by imaging studies. In the clinical setting, it is crucial to discriminate a solid serious cystadenoma from other solid pancreatic tumors. The present study reported a case of solid serous cystadenoma in which the magnetic resonance cholangiopancreatography (MRCP) findings were useful for diagnosis and decision-making regarding the surgical strategy, with a review of the previous reports of solid serous cystadenoma...

BACKGROUND: Programmed death receptor-1 blocking antibodies (anti-PD1) are a new standard of care in many cancer types. Patients benefit from improved survival but have the risk of immune-related adverse events (irAE). We evaluated if medical imaging procedures, used for anti-tumour response assessment, can detect irAEs. MATERIALS AND METHODS: All consecutive patients treated with anti-PD1 and with a medical imaging acquisition performed within 2 weeks with irAEs ≥2 were retrospectively included...

Rationale. Pancreatic neuroendocrine tumors (NETs) are rare neoplasms that develop from the endocrine tissues of the pancreas. They have a better overall prognosis than pancreatic adenocarcinoma. However, all commonly used classification systems reflect a separation between more indolent, well-differentiated tumors and far more aggressive poorly differentiated types that behave clinically more like small-cell carcinoma of the lung. Objective. To present the case of a 62-year-old man with an aggressive pancreatic NET, with liver, splenic and bone metastases who underwent multidisciplinary treatment including several lines of chemotherapy, somatostatin analogs and radiotherapy...
