title: Successful long-term management of a gonadotroph adenoma with bromocriptine.
abstract: OBJECTIVE
  To report the successful 10-year management of a gonadotroph macroadenoma with bromocriptine and review the management of gonadotroph adenomas with bromocriptine.
  
  
  METHODS
  We present a case and review the pertinent literature. The effectiveness of bromocriptine in the management of gonadotroph adenomas is evaluated.
  
  
  RESULTS
  A 62-year-old man was found to have a pituitary tumor after seeking medical assistance because of a 6-month history of headaches and blurred vision. He had decreased visual acuity and bitemporal field defects. Serum follicle-stimulating hormone (FSH) levels were increased, whereas serum luteinizing hormone and total testosterone levels were normal. Treatment with bromocriptine resulted in a decrease in serum FSH levels, complete resolution of his symptoms, and considerable improvement in his visual acuity and visual field defects. Treatment with only bromocriptine for 10 years resulted in maintenance of normal serum FSH levels and no recurrence of symptoms.
  
  
  CONCLUSIONS
  In the management of a gonadotroph adenoma, we recommend consideration of a therapeutic trial of bromocriptine. In cases that are refractory to this therapy, surgical treatment or external pituitary irradiation could then be used.
