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 .
Pseudocyst of the auricle, also known as auricular pseudocyst, endochondral pseudocyst, cystic chondromalacia, intracartilaginous auricular seroma cyst, and benign idiopathic cystic chondromalacia, [1] is a cutaneous condition characterized by a fluctuant, tense, noninflammatory swelling on the upper half of the ear, known as the auricle or pinna.
A large bore needle is used to access the identified pseudocyst, creating a fistula between the cystic cavity and either the stomach or the duodenum. [6] Plastic stents may be placed to facilitate drainage from the pseudocyst. [4] The success rate of endoscopic treatment of pseudocysts may be greater than 70%. [7]
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.
Periapical true cysts - cysts containing cavities entirely surrounded in epithelial lining. Resolution of this type of cyst requires surgical treatment such as a cystectomy. [10] Periapical pocket cysts - epithelium lined cavities that have an opening to the root canal of the affected tooth. Resolution may occur after traditional root canal ...

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 ...
