====== Lung cancer pituitary metastases ======

====== Case reports ======

A 62-year-old [[woman]] with [[multiple sclerosis]] and no history of [[malignancy]], [[incidental]]ly presented with a diffusely enlarged and homogeneously enhancing [[pituitary gland]] associated with [[stalk]] enlargement. The clinical and biochemical evaluation revealed anterior [[hypopituitarism]] and [[diabetes insipidus]]. [[Hypophysitis]] was considered the most likely diagnosis. However, rapid visual deterioration and pituitary growth raised the suspicion of metastatic involvement. A search for systemic malignancy was performed, and CT revealed a [[lung]] mass, which proved to be a [[lung adenocarcinoma]]. Accordingly, the patient was started on [[immunotherapy]]. Resection of the pituitary lesion was performed, and histopathology analysis revealed metastatic [[lung adenocarcinoma]]. Following surgery, the patient underwent [[radiotherapy]]. More than 2 years after PM detection, the patient shows a clinically relevant response to antineoplastic therapy and no evidence of PM recurrence
