chapter 12 Flashcards
Inflammation of the pancreas may be chronic or acute
Pancreatitis
Sudden onset of moderate to severe abdominal pain with radiation to back
Nausea and vomiting
History of gallstones (localized) or alcoholism
Mild fever
Increased pancreatic enzymes in blood (amylase, lipase)
Leukocytosis (increased white blood cells)
Abdominal distention
Acute pancreatitis clinical findings
Ranges from normal size to focal/diffuse enlargement
Hypoechoic texture (edema)
Borders distinct but irregular
Enlargement of head causes depression on inferior vena cava
40% to 60% have gallstones
Pancreatic duct may be enlarged
Parapancreatic fluid collections
Acute pancreatitis sonographic findings
Hemorrhagic pancreatitis
Pancreatic neoplasm
Lymphoma
Retroperitoneal neoplasm
Acute pancreatitis differential considerations
Decreased Hematocrit and serum calcium level
Intense, severe pain radiating to back, with subsequent shock and ileus
Hypotension despite volume replacement, with metabolic acidiosis and adult respiratory distress syndrome
Hemorrhagic pancreatitis Clinical findings
Depends on age of hemorrhage
Well defined homogeneous mass in area of pancreas
Hemorrhagic pancreatitis Sonographic findings
Chronic hemorrhage
Hemorrhagic pancreatitis differential considerations
See Acute pancreatitis
Phlegmonous pancreatitis clinical findings
Hypoechoic, ill defined mass
Phlegmonous pancreatitis sonographic findings
Chronic Hemorrhage
Phlegmonous pnacreatitis differential considerations
Fever, chills
Increased leukocytosis
Hypotension
Tender abdomen
Pancreatic abscess clinical findings
Hypoechoic mass with smooth borders
Thick walls
Echo-free to echogenic
Pancreatic abscess sonographic findings
Acute pancreatitis
chronic pancreatitis
Pancreatic abscess differential considerations
Seer abdominal pain radiating to back Malabsorption Fatt y stools Signs of diabetes Weight loss Jaundice Incrseaed amylase and lipase
Chronic pancreatitis clinical findings
Gland is small and fibrotic Irregular borders Mixed echogenicity Dilated pancreatic duct (string of pearls sign with dilated duct) Look for calculi within duct
Chronic pancreatitis sonographic findings
Acute pancreatits
Thrombosis of portal system
Pancreatic pseudocyst
Dilated common bile duct
Chronic pancreatitis differential considerations
