Overview
- Ultrasound, Computed tomography and MRI can differentiate between insulinoma and islet-cell hypertrophy.
CT
- Hypoglycemia caused by endogenous insulin the differential diagnosis includes insulinoma and islet-cell hypertrophy.
- Ultrasound, Computed tomography and MRI can differentiate between both.[1]
- A negative imaging study does not exclude insulinoma and patient need more tests.
- CT shows hyperattenuating on arterial phase so arterial or pancreatic phase imaging may aid in better detection. Some may show calcification.[2]
