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 .
Acute pancreatitis (AP) is a sudden inflammation of the pancreas.Causes include a gallstone impacted in the common bile duct or the pancreatic duct, heavy alcohol use, systemic disease, trauma, elevated calcium levels, hypertriglyceridemia (with triglycerides usually being very elevated, over 1000 mg/dL), certain medications, hereditary causes and, in children, mumps.
Pancreatic pseudocysts may cause abdominal pain, nausea and vomiting, a bloated feeling, and trouble eating or digesting food. They also may become infected, rupture, or block part of the intestine. Rarely, the infected pseudocyst causes jaundice or sepsis. [3]
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. It is estimated that approximately 3% of the patients with acute pancreatitis will develop an abscess. [1]
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'.
For imaging, abdominal ultrasound is convenient, simple, non-invasive, and inexpensive. [33] It is more sensitive and specific for pancreatitis from gallstones than other imaging modalities. [31] However, in 25–35% of patients the view of the pancreas can be obstructed by bowel gas making it difficult to evaluate. [30]
The colon cut-off sign is a radiographic finding seen on abdominal radiographs and computed tomography scans. It is characterized by a marked dilatation of the transverse colon, with an abrupt transition to collapsed distal colon, particularly the splenic flexure. [ 1 ]
Cullen's sign, also known as umbilical black eye, is superficial edema and bruising in the subcutaneous fatty tissue around the umbilicus.. It is named for gynecologist Thomas Stephen Cullen (1869–1953), [1] who first described the sign in ruptured ectopic pregnancy in 1916.
