The pancreas is a long, flat gland that sits behind the stomach. Its main functions are to produce digestive enzymes and hormones that regulate blood sugar levels. A cyst is a sac-like pocket of membranous tissue that contains fluid, air or other substances. There are several types of cystic growths of the pancreas, each with malignant potential that varies from nearly zero to up to 70% depending on the type. Pancreatic cysts can cause symptoms of abdominal pain, persistent nausea/vomiting, and in more serious cases, jaundice (yellowing of the skin/eyes) and weight loss.
Pancreatic neuroendocrine tumors form in neuroendocrine pancreas cells (such as islet cells). These cells make hormones that help control sugar levels in the blood. Pancreatic neuroendocrine tumors may be benign (not cancer) or malignant (cancer). They are much less common than pancreatic exocrine tumors and have a better prognosis.
This is sinusitis of all your sinuses. Sinusitis is an inflammation of the tissues in your sinuses (spaces in your forehead, cheeks and nose usually filled with air). It causes facial pain, a stuffy or runny nose, and sometimes a fever and other symptoms. It’s usually caused by the common cold, but other viruses, bacteria, fungi and allergies can also cause sinusitis.
The pancreas is a long, flat gland that sits tucked behind the stomach in the upper abdomen. Its main function is to produce enzymes that help with digestion and hormones that help regulate the way the body processes sugar. Calcium can build up in parts of the pancreas due to an unknown cause or from conditions including alcoholic pancreatitis (inflammation of the pancreas), cystic fibrosis, aging and rarely, cancer.
Lymph nodes are small bean-shaped structures that are part of the body's immune system. The mesentery is the tissue that holds the small intestines. The retroperitoneal lymph nodes drain lymphatic fluid from the abdominopelvic gastrointestinal system as well as the skin, muscles, organs and deep tissues of the posterior abdominal wall. The main symptom for panniculitis (inflammation of subcutaneous fat), if it is acute, is painful or tender bumps called nodules that form in the layer of fat under your skin. Systemic symptoms may also be present and can include fatigue, fever, a general feeling of being unwell (malaise), joint and muscle pain, abdominal pain, nausea, vomiting, and/or weight loss.
Pancreatic pseudocyst describes a fluid collection without the normal lining of cells that a cyst would have. Any injury to the pancreas, such as inflammation of the pancreas (pancreatitis) or physical trauma, can damage the pancreatic ducts and cause a pseudocyst to form.
