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.
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 .
This method is the second of two less invasive surgeries used to drain pseudocysts and can be performed by a single surgeon because of the advanced tools. The pseudocyst is identified and accessed using laparoscopic techniques. Once the pseudocyst cavity is located, it is entered and aspirated, and an opening is created into the stomach for ...
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.
Pseudocysts [ edit ] A pancreatic pseudocyst is a circumscribed collection of fluid rich in amylase and other pancreatic enzymes , blood and necrotic tissue , typically located in the lesser sac .
Also, non-neoplastic cysts include pseudocyst, retention cyst, benign epithelial cysts, lymphoepithelial cysts, squamous lined cysts (dermoid cyst and epidermal cyst in intrapancreatic accessory spleen), mucinous nonneoplastic cysts, and lymphangiomas. [3] A pancreatic cyst is a fluid filled sac within the pancreas.
The traumatic bone cyst, also referred to as a simple bone cyst or hemorrhagic cyst, is a pseudocyst that most commonly affects the mandible of young individuals. It is a benign empty or fluid-containing cavity within the mandible body that does not have evidence of a true epithelial lining.
It is a classed as a pseudocyst, [1] since there is no epithelial lining or fluid content. This defect is usually considered with other cysts of the jaws, since it can be mistaken for such on a radiograph. Two classification systems were proposed to categorize Stafne bone cavity based on its depth [2] and content. [3]
