Abscesos hipofisarios: estudio de siete casos

Pituitary abscesses are rare but should be included in the differential diagnosis of sellar masses. Although preoperative diagnosis is difficult, diabetes insipidus, thickening of the stalk and peripheral contrast uptake help to differentiate these abscesses froma denomas. Treatment is surgical and some patients require more than one intervention. Visual function usually returns to normal. Endocrine alterations are permanent.
