Pituitary metastases.
Over the past 12 years we encountered three histologically confirmed pituitary metastases. Primary cancer had been diagnosed and treated previously in only one patient. In the remaining two a transsphenoidal operation provided the initial diagnosis of metastasis, and the primary lesion was subsequently detected at autopsy in one. In two of the three patients symptoms and signs of pituitary dysfunction were the first manifestations of the malignant disease. The main symptoms and signs were impairment of visual acuity, visual field defect, headache, adenohypophyseal insufficency and diabetes insipidus. A sellar mass was demonstrated by CT or MRI in all patients. The tumours were all completely extirpated by subfrontal route in one case and transsphenoidally in the remaining two patients. Following surgery the presenting symptoms improved satisfactorily in all patients.
