Radiology of acute pancreatitis today: the Atlanta classification and the current role of imaging in its diagnosis and treatment.

Acute pancreatitis is common and requires multidisciplinary management. The revised Atlanta classification, published in 2012, defines the terminology necessary to enable specialists from different backgrounds to discuss the morphological and clinical types of acute pancreatitis. Radiologists' role depends fundamentally on computed tomography (CT), which makes it possible to classify the morphology of this disease and to predict its clinical severity by applying imaging severity indices.

Focal Pneumatosis cystoides intestinalis: optic colonoscopy and virtual colonoscopy features.

Pneumatosis intestinalis refers to lineal or cystic gas collections in the intestinal wall. Pneumatosis cystoides intestinalis (PCI) is a benign primary cause. This is a rare disease characterized by multiple gas cysts in the submucosa or subserosa, principally within the colon.

Diagnosis of Mesenteric Ectopic Pancreas by Secretin-Enhanced Magnetic Resonance Cholangiopancreatography.

Ectopic pancreas (EP) is defined as pancreatic tissue found outside its usual anatomical position, with no ductal or vascular communication with the native pancreas.We report the case of a 59-year-old woman with a mesenteric jejunal EP initially suspected on computed tomography and confirmed by secretin-enhanced magnetic resonance cholangiopancreatography.Mesenteric EP is a very rare finding with nonspecific clinical presentation, so that, classic radiological findings have not been well described previously.

Type II intrapancreatic choledochal malignant cyst in adults: duodenopancreatectomy.

A 62-year-old female patient was admitted for abdominal pain and vomiting. Imaging tests revealed a solid-cystic lesion at the head of the pancreas communicating with the distal bile duct. A Todani type II choledochal cyst was diagnosed with neoplastic degeneration after cytological diagnosis with endoscopic ultrasound-guided puncture.
