A 14-year-old domestic shorthair cat was presented with hypoglycaemia and seizures of several weeks duration. Bloodwork revealed hypoglycaemia (1.83 mmol/l; reference range 4.22-8.05 mmol/l) with concurrent normal insulin levels (171 pmol/l; reference range 72-583 pmol/l). An insulinoma was suspected and medical and dietary management were attempted with minimal success. An exploratory laparotomy was performed and a single, well-defined mass was found within the left lobe of the pancreas. The mass was removed and histologically classified as an islet cell carcinoma, consistent with an insulinoma. The cat had an episode of presumed postoperative pancreatitits, but recovered with appropriate treatment. The cat has had no clinical signs of recurrence of greater than 32 months postsurgery. There are only four cases of insulinoma in cats reported in the literature. All prior insulionomas reported were in older cats and were malignant in character, which is similar to the reports in the dog. This case is unique because of the apparent lack of local recurrence and development of metastatic disease, leading to the prolonged survival.
ALTHOUGH the cases and observations which I am about to lay before the Society, are stated to be connected with derangement of the pancreas and duodenum; yet they are chiefly intended to call the attention of the Members to a particular symptom in disease, which I believe to have been but little noticed. In this I may be mistaken, but at all events it is not a frequent symptom, and the present paper will serve as an additional record. of its existence, even though I should fail, as I fear I shall, to bring forward any thing conclusive in elucidation of the morbid state, or even demonstrative of the organ, on which it depends, and I am the less scrupulous in submitting these cases to the Society because they are not without interest, independently of the direct VOL.

This case report describes a previously unreported congenital malformation, an umbilico-billary fistula, in a dog. A one-year-old male bulldog was diagnosed with umbilico-billary fistula using fistulography. Treatment involving surgical removal of the fistula was straightforward and resulted in clinical resolution of the problem.
