A Rare Case Report - Big Insulinoma of Pancreas

Insulinomas account for 60 % of islet cell tumours (ICT) and are typically hypervascular, solitary small tumours, 90 % of which measure less than 2cm and 30 % measuring less than 1cm in diameter. Approximately 10 % are multiple, 10 % are malignant and 4-7 % are associated with MEN I, these tumours are usually multiple and can be malignant in up to 25 %. The tumour is characterized by endogenous hypersecretion of insulin and the subsequent development of symptoms of neuroglycopenia and symptoms resulting from the catecholaminergic response, which may not always be present. Early localisation of the disease is essential to prevent lethal hypoglycaemia. We report a case of big insulinoma of size of 4 cm in a 45 year old female which was diagnosed on triple phase CT Scan abdomen and was treated with distal pancreatectomy along with splenectomy.
