UNASSIGNED: @entity3 to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of @entity5 @entity1 , and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of @entity1 with known @entity5 , but, generally, asymptomatic with respect to pituitary involvement. The most common primary sites are breast in @entity1 and lung in @entity1 . We present the case of a 64-year-old @entity1 with clinical visual changes, @entity2011 , @entity4683 , and decreased level of consciousness whose tests showed pan- @entity4614 , @entity3489 and low urine specific gravity, and extensive mass in sellar region. @entity2010 was confirmed and treated, @entity1374 were corrected and then the @entity1 underwent resection by transsphenoidal surgery. The histopathological and immunohistochemistry analysis revealed @entity977 . Subsequently, a chest CT scan showed pulmonary mass consistent with @entity5 . Despite the water and electrolyte correction and intravenous glucocorticoid replacement, the @entity1 continued to show decreased level of consciousness due to compression of the brain stem by the pituitary mass, evolving to death. The purpose is to call attention to the differential diagnosis of invasive lesions of the sellar region, mainly in individuals over 50 years and/or when associated with @entity2010 , as it may be a case of @entity3 , although there is no known @entity5 .
