Pituitary apoplexy in an adolescent with prolactin-secreting adenoma.

A 14.8-year-old girl was treated with bromocriptine for a prolactin-secreting adenoma. She suddenly developed headaches, vomiting, fever and meningeal syndrome. This was associated with corticotropin, thyrotropin and gonadotropin deficiencies. Magnetic resonance imaging showed peripheral enhancement and a central hyposignal suggesting intra-adenoma hemorrhage and then disappearance of the adenoma. Hydrocortisone was initiated in emergency to prevent any risk to life.
