A pancreatic pseudocyst is a circumscribed collection of fluid rich in pancreatic enzymes, blood, and non-necrotic tissue, typically located in the lesser sac of the abdomen. Pancreatic pseudocysts are usually complications of pancreatitis , [ 5 ] although in children they frequently occur following abdominal trauma .
A pseudocyst is a cystic lesion that may appear as a cyst on scans, but lacks epithelial or endothelial cells. [4] An acute pancreatic pseudocyst is made of pancreatic fluids with a wall of fibrous tissue or granulation. [citation needed] Pseudocysts may form in a number of places, including the pancreas, abdomen, adrenal gland, and eye.
To further diagnose a pancreatic pseudocyst an abdominal CT scan, MRI or ultrasound can be used. [5] Emergency surgery may need to be performed if there is a rupture of the pseudocyst. This can be detected from symptoms of bleeding, shock, fainting, fever and chills, rapid heartbeat, or severe abdominal pain.
A pancreatic cyst is a fluid filled sac within the pancreas. The prevalence of pancreatic cysts is 2-15% based on imaging studies, but the prevalence may be as high as 50% based on autopsy series. [1] Most pancreatic cysts are benign and the risk of malignancy (pancreatic cancer) is 0.5-1.5%.
Ultrasonography can be used to visualize pancreatic pseudocysts or aneurysm of the peripancreatic arteries. Doppler ultrasound or dynamic ultrasound has been reported to be diagnostic. Contrast-enhanced CT is an excellent modality for demonstrating the pancreatic pathology and can also demonstrate features of chronic pancreatitis, pseudocysts ...
Intraductal papillary mucinous neoplasm (IPMN) is a type of tumor that can occur within the cells of the pancreatic duct. IPMN tumors produce mucus, [1] and this mucus can form pancreatic cysts. [2] Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. [1]
The first recorded case of pancreatic injury was published in The Lancet in 1827. [8] At the time, death as a result of injury was deemed to be "universal". [8] The first successful surgery to repair a transected pancreas was performed in 1904 by Garré, who reported the case the following year. [5] [9] [10]
Cystic lesions of the pancreas are a group of pancreatic lesions characterized by a cystic appearance. They can be benign or malignant. [citation needed]Cystic lesions are found in 20.6% of all pancreatectomy specimens.
