Pituitary adenoma results in the empty sella syndrome.
A 69-year-old female was treated for hyperthyroidism and hypertension. In August 1984, she suddenly began suffering from polyuria and polydipsia. In October, she exhibited fever, headache, vertigo, and poor appetite, probably due to pituitary apoplexy. Her endocrine function was normal, except for partial diabetes insipidus. A contrast-enhanced CT brain scan revealed a pituitary adenoma with a ring-enhanced outer edge and a central low-density area. The MRI scan also indicated cystic adenoma. A CT scan examination repeated 6 months later showed an empty sella with a markedly decreased pituitary adenoma. This case report demonstrates that some empty sella are the final result of pituitary adenoma bleeding or infarction.
