An accessory spleen is a small nodule of splenic tissue found apart from the main body of the spleen. Accessory spleens are found in approximately 10 percent of the population [1] and are typically around 1 centimetre in diameter. They may resemble a lymph node or a small spleen. They form either by the result of developmental anomalies or ...
It is usually solitary and found in the body or tail of the pancreas, and may be associated with von Hippel–Lindau syndrome. [2] In contrast to some of the other cyst-forming tumors of the pancreas (such as the intraductal papillary mucinous neoplasm and the pancreatic mucinous cystadenoma), serous cystic neoplasms are almost always entirely ...
The splenic lymph nodes are found at the splenic hilum and in relation to the tail of the pancreas (pancreaticolienal lymph nodes). [1] [2] Their afferents are derived from the stomach, spleen, and pancreas. The splenic lymph nodes empty into the suprapancreatic, infrapancreatic and omental lymph nodes, which then drain to the coeliac nodes and ...
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%.
Hemosuccus pancreaticus is a rare cause of hemorrhage in the gastrointestinal tract.It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine.
[citation needed] Indications for surgical resection include obstructive jaundice, an enhancing mural nodule >5 mm, and pancreatic duct dilation (>10 mm). [ 12 ] Surgery can include the removal of the head of the pancreas (a pancreaticoduodenectomy ), removal of the body and tail of the pancreas (a distal pancreatectomy ), or rarely removal of ...
A periumbilical mass is not always a Sister Mary Joseph nodule. Other conditions that can cause a palpable periumbilical mass include umbilical hernia, infection, and endometriosis. Medical imaging, such as abdominal ultrasound, may be used to distinguish a Sister Mary Joseph nodule from another kind of mass. [2]
A pancreatic tumor is an abnormal growth in the pancreas. [1] In adults, almost 90% are pancreatic cancer and a few are benign. [1] Pancreatic tumors are rare in children. [1] Classification is based on cellular differentiation (ductal, acinar, neuroendocrine, other) and gross appearance (intraductal, cystic, solid). [1]
