Pituitary metastasis of lung carcinoma presenting as diabetes insipidus: Case report

Metastasis to Pituitary gland is an extremely rare condition. Patients are usually asymptomatic and
imaging studies often miss the lesion. Pituitary metastases so far reported are largely from autopsies
done for unrelated reasons. Here, we describe a case of pituitary metastasis, presented with diabetes
insipidis, underwent surgery for removal of pituitary tumor and diagnosed as metastatic lung cancer using
immunohistochemical studies.
