Further evaluation led to the diagnosis of Lymphocytic hypophysitis that recrudesced despite treatment with corticosteroids. Consequently, she was treated with transsphenoidal surgical resection, and postoperative histopathological evaluation indicated that this is a case of granulomatous not lymphocytic hypophysitis. The patient recovered perfectly after surgery with no residual symptoms on follow-up. These findings stress on the profound similarities between both pathologies and supports the theory that they are .different phases of the same disease process rather than different diseases.
