Abstract


Sellar region hosts a wide range of different types of lesions. Most of these lesions present with mass effect symptoms and, often, with symptoms related to hormonal disturbances, mimicking a pituitary neuroendocrine tumour (PitNET). We report two cases of sellar lesions with clinical and radiological features suggestive for PitNET. Histological and immunohistochemical analysis led to a diagnosis respectively for lymphocytic hypophysitis (LH) and meningioma.


Keywords
