Diagnosis and treatment of the pituitary metastases.
Three cases of pituitary metastases were reported. They all had operations and the pathological examination confirming the diagnosis. The clinical features of diabetes insipidus and extraocular nerve palsy were presented. In two cases, the original tumors were bronchioloalveolar carcinoma; in the other one, the original tumor was unknown. All three cases had poor outcome. These cases illustrate the fact that a pituitary metastasis can closely mimic a pituitary benign tumor, such as pituitary adenoma. Especially in the presence of suggestive symptoms such as diabetes insipidus and/or cranical nerve paralysis, the possibility of metastatic disease in the differential diagnosis of a pituitary mass should always be considered.
