title: Hyperthyroidism due to a thyrotrophin-secreting microadenoma.
abstract: We report a 63-year-old female with a TSH-secreting pituitary adenoma causing hyperthyroidism. This case is apparently unique, and challenges the present concept of dividing patients with inappropriate TSH secretion into tumour and non-tumour groups on the basis of conventional pituitary fossa radiology.
