title: Suprasellar extension of tumour associated with increased cerebrospinal fluid activity of LH and FSH.
abstract: A 65 year old man with pituitary adenoma, partial hypopituitarism and normal serum FSH and LH concentration is described. LH (but not FSH) partially increased following the administration of LH-RH. Subsequent FSH and LH assays of the cerebrospinal fluid, however, showed a high and correctly predicted suprasellar extension of the tumour.
