Treatment Outcome of Endoscopic Ultrasound Radiofrequency Ablation for Incidentaloma Pancreatic Neuroendocrine Tumor in Young Female Patient: A 2-year Follow-Up

Abstract

Pancreatic neuroendocrine tumors (PNETs) or islet cell tumors are neuroendocrine neoplasms that arise from cells of the endocrine and nervous system within the pancreas. Patients with PNET sometimes do not show any symptoms, known as nonfunctioning (NF) sporadic PNET. It is still debatable regarding the best approach in the NF for small PNET. Currently, the surgical approach is considered the best; however, it is a highly invasive procedure, and it has a potentially high risk of complications as it requires a skilled and experienced operator. Herewith, we reported a 48-year-old female with incidentaloma of nonfunctioning PNET (NF-PNET) whose tumor has been successfully treated with endoscopic ultrasound guided radiofrequency ablation (EUSRA). There was no adverse event observed during and after the EUS procedure, and even 1 week after the procedure. One year later, abdominal magnetic resonance imaging (MRI) examination was carried out and size of the tumor was significantly getting smaller where it could hardly be seen anymore. After 2 years of follow-up, the latest abdominal MRI study showed no solid part of the tumor could be seen anymore. In conclusion, EUSRA can be an alternative option for incidentaloma of NF-PNET management.
