  • Insulinoma

Our colleague Mayra did an ultrasound scan and characterised the mass prior to surgery for removal of the “limb” of the pancreas containing the insulinoma. The mass was approximately 1.5cm diameter and in the right limb of the pancreas.

The mass was identified and carefully dissected with apparent gross margins. The associated part of the pancreas was removed to avoid risk of leaving an area of pancreas still producing enzymes but with no effective duct drainage into the intestines.

Histology was reported as Insulinoma, a carcinoma arising from the Beta cells in the pancreatic islets. This is a potentially malignant tumour which may spread to the lymph nodes, liver, mesentery and omentum. It was not confirmed that we had been able to achieve surgical margins around the mass and so regrowth was a possibility.

She did really well post op, but developed diabetes about 5 months post-op. The owner controls this with insulin injections.

About a year on she’s still doing well and we plan to re-scan her before too long.
