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.
Symptomatic pancreatic pseudocysts are an indication a cystogastrostomy needs to be performed. Pancreatic pseudocysts are chronic collections of pancreatic fluid encased by a wall of nonepithelialized granulation tissue and fibrosis. They can be caused by leakage of the pancreatic duct, or as a result of inflammatory pancreatitis. [4]
Pancreatic abscess is a late complication of acute necrotizing pancreatitis, occurring more than 4 weeks after the initial attack.A pancreatic abscess is a collection of pus resulting from tissue necrosis, liquefaction, and infection.
Severe pancreatitis can cause organ failure, necrosis, infected necrosis, pseudocyst, and abscess. If diagnosed with severe acute pancreatitis, people will need to be admitted to a high-dependency unit or intensive care unit. It is likely that the levels of fluids inside the body will have dropped significantly as it diverts bodily fluids and ...
Pancreatic pseudocysts are benign, with a risk of malignant progression of 0%. [1] Pseudocysts are associated with acute or chronic pancreatitis and the cysts usually commnicate with the main pancreatic duct. They usually resolve spontaneously and are unilocular (not septated; ie. do not have walls separating parts of the cyst) and may be ...
The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots. The resulting pulpal necrosis causes proliferation of epithelial rests of Malassez which release toxins at the apex of the tooth. The body's inflammatory response will attack the source of the toxins, leading to ...
Most commonly, it is used in contradistinction to a "walled-off" pus-filled collection , although a phlegmon may progress to an abscess if untreated. A phlegmon can localize anywhere in the body. [1] The Latin term phlegmōn is from Ancient Greek φλέγω (phlégō) 'burn'.
