Conclusion:Pituitary abscess should be considered when patients presented diabetes insipidus,hypopituitarism,sella bone erosion and sella neoplasm similar to a cyst tumor in CT or MRI.
Conclusion The change of the relationship of the hapothalamus-pituitary-ovary and the hypotrophy of the pituitary may not cause the morphologic change of sella turcica.
In addition, MRI and CT scans can show ring enhancement or halo around a partially or completely empty sella turcica, called the 'pituitary ring sign'.
In severe cases, severe destruction and scarring can lead to an empty sella turcica which is when the pituitary gland shrinks and flattens into the skull.
