Are there any specific CT scans available to detect insulinoma?
CT scan with contrast
Hi and welcome.
CT scan is gold standard for detecting insulinoma and other pancreatic tumors but is should be done with intravenous contrast. also,as a routine part of work up ,is endoscopic ultrasound which has 85% sensitivity. MRI and somatostatin scintigraphy are used when finding is doubtful. all in all, ct scan, abnormal glucose and insulin fluctuations and clinical picture should be enough to establish right diagnosis. Wish you good health. Regards
no,there is no pancreas specific ct scan. there is abdominal ct scan with contrast which visualize all intrabdominal organs and then everything can be magnified and examined in details.so you 've done test that is enough to evaluate pancreas lesions.
You re welcome
you 're welcome
few possible causes
Insulinoma is one of them but other neuroendocrine tumors in small bowels or duodenum may lead to it as well. Also, hormonal imbalance, not just insulin, but cortisol or steroids, may be caused by disorders or adrenal glands.
Liver cirrhosis, Gastric dumping syndrome after surgeries may cause it as well.
Sometimes no cause is found and then it is called as Idiopathic Postprandial Syndrome or reactive hypoglycemia and it should be treated with diet rich in sugar or glucagon injections.
Wish you good health.
both is possible
It can be both. It is not easy to define exact cause, but you should first rule out neuroendocrine tumors so do lab tests: chromogranin A (CgA) in
urine and 5-hydroxyindoleacetic acid. I dont think endoscopy is required if ct scan was fine. But you should see diabetologist and do extensive laboratory work up to define triggers for glucose fluctuations. This may not be just gastrointestinal cause but also disorders in hypotalamus, kidneys and adrenal glands
