-===Diagnostic imaging===
+==Case Studies==
-The insulinoma might be localized by non-invasive means, using [[ultrasound]], [[CT scan]], or by [[MRI]] techniques.<br/>
+[[Case study one|Case #1]]
-Sometimes, [[angiography]] with percutaneous transhepatic [[pancreatic vein]] [[catheterization]] to sample the blood for insulin levels is required. [[Calcium]] can be injected into selected arteries to stimulate insulin release from various parts of the pancreas, which can be measured by sampling blood from their respective veins.  The use of calcium stimulation improves the specificity of this test.<br/>
-During surgery to remove an insulinoma, an intra-operative ultrasound can sometimes localize the tumour, which helps guide the surgeon in the operation.
-==Treatment==
-The definitive management is surgical removal of the insulinoma.  This may involve removing part of the pancreas as well ([[Whipple procedure]] and distal [[pancreatectomy]]).<br>
-Medications such as [[diazoxide]] and [[somatostatin]] can be used to block the release of insulin for patients who are not surgical candidates or who otherwise have inoperable tumours.<br/>
-[[Streptozotocin]] is used in [[islet cell carcinoma]]s which produce excessive insulin.  Combination [[chemotherapy]] is used: either [[doxorubicin]] + streptozotocin, or [[fluorouracil]] + streptotozocin in patients where doxorubicin is contraindicated.[http://www.cancer.gov/cancertopics/pdq/treatment/isletcell/HealthProfessional/page6] <br>
-In metastasizing tumours with intrahepatic growth, [[hepatic artery|hepatic arterial]] occlusion or [[embolization]] can be used. [http://www.nci.nih.gov/cancertopics/pdq/treatment/isletcell/Patient/page5]
-==Prognosis==
-Most patients with benign insulinomas can be cured with surgery.  Persistent or recurrent hypoglycemia after surgery tends to occur in patients with multiple tumours.  About two percent of patients develop [[diabetes mellitus]] after their surgery.
-==History==
-Hypoglycemia was first recognized in the 19th century.  In the 1920’s, after the discovery of insulin and its use in the treatment of diabetics, hyperinsulinism was suspected to be a cause of hypoglycemia in non-diabetics. The first report of a surgical cure of hypoglycemia by removing an islet cell tumour was in 1929.
