Diagnosis can occur via two distinct ways. The first is inclusive of a patient initially diagnosed with benign<unk> . After the initial presentation of hypoglycemic symptoms, blood tests are taken in order to confirm hypoglycemia. A glucose, insulin and C-peptide are drawn. Initial diagnoses routinely also include a pre-operative CT to confirm an<unk> . Upon completion of bloodwork and required radiology, majority of<unk> s are diagnosed if present. The most common treatment option for those diagnosed with benign<unk> s are treated by isolated removal of the<unk> . But, some of these patient cases progress and metastasize into a<unk> . This occurs when cancerous cells break away from the<unk>  and enter the bloodstream or lymphatic system. Thus, it is possible to later develop malignancy after the initial diagnosis of<unk> , and even after operative removal of the<unk> . In these cases, the most common site of metastases is the liver, as well as the lymph nodes. However, the second type of diagnoses of<unk>  involves a patient who presents with symptoms of an<unk> , and is taken for a pre-operative CT. Upon reading the radiology report, a<unk>  can be found and diagnosed immediately. Blood tests The following blood tests are needed to diagnose<unk> : * Glucose * Insulin * C-peptide A significant blood glucose level 3 μIU/mL, and C-peptide level > 0.6 ng/mL is indicative of hypoinsulinemic hypoglycemia. Diagnostic Imaging Less invasive imaging such as US, CT scan and MRI can be utilized to confirm the presence of an<unk> . More specifically, a transabdominal ultrasound and CT are typically the first diagnostic images ordered. Further testing includes an endoscopic ultrasound or MRI.
