Paroxysmal "funny turns" in an elderly woman--a 95-year-old with an insulinoma

A 95-year-old woman was admitted to hospital with a fractured neck of femur following a fall. There was no past history of note other than numerous episodes of "funny turns" preceding falls some of which resulted in fractures. During her admission she had a "funny turn". Immediate investigations revealed hypoglycaemia and subsequent biochemical abnormalities, most likely due to a benign endocrine tumour--an insulinoma.
