Introduction : Insulinomas are the most common functional endocrine neoplasm of the pancreas and cause hypoglycemia by releasing insulin.

Methods : They constitute 1% to 2% of the pancreatic tumors and occur in 1-4 people per million population. Hypoglycemic symptoms are either autonomic or neuroglycopenic . Common autonomic symptoms are palpitations, tremors, diaphoresis; whereas neuroglycopenic symptoms include behavioral changes, confusion, headache, visual disturbances, seizures and coma .Diagnosis of the suspected cases is by various endocrine tests including tests that are often performed to satisfy the criteria of Whipple's triad. For localisation of the Insulinomas various non invasive procedures like CT scan and MRI are used. Some invasive test for localisation are EUS and arterial stimulation venous sampling. The range of techniques available for the localisation of insulinoma means that blind resection of the pancreas can be avoided. A high percentage of patients with insulinoma can be cured by surgical resection

Results : We present one case of a young lady who presented with dizziness and altered mental state followed by unconsciousness; and was brought to the emergency room where she was found to have hypoglycemia. Patient promptly responded to intravenous dextrose. She was investigated by various endocrine tests to find the cause of hypoglycemia and this was followed by imaging test to localise the pancreatic tumour. Patient underwent laparoscopic resection of the tumour located near the junction of body and tail of pancreas. Patient had unremarkable postoperative stay and was discharged home. She has been symptom free in the last 3 months of follow up.

Conclusions : .
