Background: Pituitary metastasis as a presenting manifestation of silent systemic malignancy is rare. We describe four such cases. Materials and Methods: Four patients (0.7%) of malignancy with pituitary metastasis out of 540 patients of sellar mass within a period of 10 years were analyzed for clinical, hormonal and radiological findings. Result: The age range of these patients was 39-60 years with lag time ranging from 2to 5 months. Pituitary pathology was presenting manifestation in all 4 patients including diabetes insipidus, ophthalmoplegia and variable anterior pituitary hormone deficiency. 2 patients had bronchogenic carcinoma and one each had squamous cell and adenocarcinoma with unknown primary. Diagnosis of pituitary metastasis was confirmed in three on pituitary mass histopathology and in one it was based on rapidly appearing mass in a short time. Conclusion: Rapidly appearing mass in the sellar region, short lag time,sudden onset of ophthalmoplegia, -symptoms and signs disproportionate to the size of mass, presence of diabetes insipidus and destroyed but normal sized sella should invoke the suspicion of pituitary metastasis.
