Pituitary abscess:Report of three cases

Pituitary abscess is a rare but potentially life-threatening disease.Headache,visual disturbance,and hypopituitarism are the most common presenting symptoms of pituitary abscess.On magnetic resonance imaging(MRI),pituitary abscess may present as a round sellar cystic lesion,hypo-or isointense on T1 imaging and hyper-or isointense on T2 imaging with peripheral gadolinium enhancement.Diagnosis usually is made during surgical exploration when pus is found in a cystic lesion.The mainstay of treatment is transsphenoidal surgical resection in combination with antibiotic therapy,although a craniotomy approach is warranted in select conditions.Here we report 3 cases of pituitary abscess in our hospital and review the literatures.
