Successful Treatment of Benign Insulinoma by Transcatheter Angioembolization

Background/Objective

Evidence on the efficacy and safety of minimally invasive treatment for insulinoma has increased over the past decade to the point of becoming a recommendation in clinical practice guidelines for the management of this type of neuroendocrine tumor.

Case Report

We describe the case of an elderly male patient with multiple comorbidities and recurrent isolated insulinoma of 3.7 × 3.5 cm involving the uncinate process of the pancreas and contacting the splenomesenteric confluent many years after first resection, in whom, after refusing surgical management, was performed as successful arterial embolization of the pancreatic tumor.

Discussion

When addressing this pathology, it is common to encounter patients who are not candidates for surgical management, either due to the presence of comorbidities, the location of the tumor in relation to vascular structures, or refusal of the intervention. Therefore, it is important to be aware of the different therapeutic options in localized and metastatic disease.

Conclusion

Minimally invasive procedures are positioned as an effective alternative for the treatment of the hormonal overproduction in patients with insulinoma.
