  • Title: Pre- and peroperative misdiagnosed sellar tumour.
    Author: Selvais P, Raftopoulos C, Godfraind C, Duprez T, Thauvoy C, Buysschaert M, Maiter DM.
    Journal: Acta Clin Belg; 1998 Jun; 53(3):203-5. PubMed ID: 9701857.
    Abstract:
    We describe the case of a 76-year old woman complaining of headaches and progressive sight loss. Cerebral CT scan and MRI disclosed a large sellar tumour. Endocrine evaluation showed no evidence of pituitary hypersecretion, but a slight hyperprolactinemia related to stalk compression. A non-functioning pituitary adenoma was suspected. The pathological diagnosis was however a meningioma. In the literature, about 5% of sellar tumours are not pituitary adenomas and this is an alternate diagnosis to consider in the presence of non-secreting macroadenomas.
