upper abdominal cystic mass
Introduction
Introduction Abdominal mass refers to an abnormal mass that can be accessed during abdominal examination. Common causes include swelling of organs, swelling of hollow organs, tissue hyperplasia, inflammatory adhesions, and benign and malignant tumors. Upper abdominal cystic mass is the main sign of clinical manifestations of hepatic hydatid cysts. The clinical manifestations are not obvious, more common in young and middle-aged, initial asymptomatic, with cyst enlargement and upper abdominal mass, abdominal distension, abdominal pain, such as located in the right upper liver, showing diaphragmatic elevation, may have respiratory symptoms. Many patients have had allergic reactions. A small number of jaundice can be produced by cystic compression of the biliary tract. There are also complication of infection or cholangitis or septicemia. Respiratory symptoms or bronchial biliary fistula can occur in the chest. The main signs are upper abdominal cystic masses, and those located above the swelling only see hepatomegaly. Corresponding signs may appear in patients with complications.
Cause
Cause
1. Upper right abdomen mass
(1) Liver enlargement: such as hepatitis, liver abscess, liver tumor, liver cyst and so on.
(2) gallbladder enlargement: such as acute cholecystitis, gallbladder hydrocephalus, gallbladder hemorrhage, cholestatic cystic cyst, congenital choledochal cyst, primary gallbladder cancer, gallbladder torsion and so on.
(3) Hepatic curvature of colon cancer.
2. Middle and upper abdominal masses
(1) stomach mass: such as ulcer disease, gastric cancer and other benign and malignant tumors in the stomach, gastric mucosal prolapse, stomach stone disease.
(2) pancreatic masses: such as acute pancreatitis, pancreatic cysts, cystic adenoma of the pancreas, pancreatic cancer, etc.
(3) The left hepatic lobe is swollen.
(4) Mesenteric and omental mass: such as mesenteric lymph node tuberculosis, mesenteric cyst and so on.
(5) Small intestine tumors: such as small intestine malignant lymphoma, small intestine cancer, and other rare small intestine tumors.

A detailed understanding of medical history is important for the diagnosis of abdominal diseases. The growth rate of the tumor, accompanied by symptoms, can provide some clues to the diagnosis. Gastric cancer often has progressive appetite loss, anemia, and weight loss in the medical history. Gallbladder enlargement, accompanied by progressive jaundice without abdominal pain often suggests pancreatic head cancer. Gallbladder enlargement, intermittent jaundice with paroxysmal right upper abdominal pain and fever are more common in cholelithiasis. Liver enlargement, such as chronic heart failure in the history of the liver may be hepatic congestion. Inflammatory masses often have fever and a history of pain in the corresponding area. The disease has a long history, and the growth rate of the tumor is slow, without other symptoms, and it is often a benign mass.
