Small pancreatic insulinoma: Successful endoscopic ultrasound-guided radiofrequency ablation in a single session, using a 22G fine needle

A 63-year-old woman, morbidly obese, with clinical symptoms of periodic hypoglycemic episodes, was diagnosed with an insulinoma in pancreatic body that had not been detected by previous computed tomography and magnetic resonance. This neuroendocrine tumour was identified by EUS as a hypoechoic lesion with some iso-hyperechoic tracts, measuring 9 x 10 mm, and 4-5 mm from splenic vessels (Figure 1a).
