false
abnormal pancreas displaces duodenum __
peripherally
The portal vein crosses _- to the body of the pancreas
dorsal

how does pancreatitis look on ultrasound
hypoechoic mass dorsomedial to duodenum, caudal to stomach
What wrong and how do you know
pancreatitis- C- shaped duodenum pushed to periphery
ultrasound of pancreas what wrong
pancreatitis
which is more likely to have more fluid- pancreatitis or pancreatic neoplasia on ultrasound
neoplasia
what are some complications of pancreatitis
- Pseudo cyst
- Abscessation
- Bile duct obstruction
Patient dx with pancreatitis what is indicated by 1
pseudocyst
what are some examples of neoplasias of pancreas
- Adenocarcinoma
- Insulinoma
what do you see with adenocarcinoma of pancreas on ultrasound
- Carcinomatosis
- Hepatic metastasis
- Fluid
what do you see on ultrasound of insulinoma and what is classic BW finding
hypoechoic mass
Hypoglycemia
Ultrasound of pancreas what wrong
metastatic carcinoma- very nodular mesentery
Also fluid
patient presents with extreme hypoglycemia- take ultrasound of pancreas and see this what likely dx
Insulinoma
