Spontaneous regression of a pituitary cyst: report of two cases.
Two unusual cases of pituitary cysts are described. Both patients presented with sudden onset of severe headache, and magnetic resonance imaging (MRI) demonstrated pituitary cysts, which regressed over months. Although the precise etiology of the cysts was unproven, the cystic lesions in our patients are thought to have shrunken after "pituitary apoplexy."
