Prolactin-secreting pituitary microadenomas: inaccuracy of high-resolution CT imaging.
Computed tomographic (CT) and surgical findings were correlated retrospectively in 51 patients with preoperative diagnoses of prolactin-secreting pituitary microadenomas. Thirty-nine had microadenomas at surgery. Twenty-three had identifiable discrete lesions. Of these, 21 had microadenomas and two did not; these two groups could not be distinguished reliably. Six patients with proven microaden...
متن کاملMR imaging of prolactin-secreting microadenomas.
Eight proven and three presumed prolactin-secreting microadenomas were studied with magnetic resonance (MR) imaging. All 11 cases had CT evidence of a tumor. Technical factors for MR included use of 1.3-1.5 T MR systems, 3 mm slice thickness, short repetition time (TR) (T1-weighted) and long TR (T2-weighted) spin-echo pulse sequences. Six microadenomas were demonstrated with MR. Four tumors had...
متن کاملMR of corticotropin-secreting pituitary microadenomas.
PURPOSE To assess the accuracy of MR in the preoperative identification of corticotropin-secreting pituitary microadenomas. METHODS Twenty-six patients with clinical and biochemical evidence of pituitary-driven Cushing disease in whom MR of the seller region was performed were selected for this study. The MR examinations were retrospectively evaluated by a neuroradiologist who was aware of th...
متن کاملProlactin secreting pituitary carcinoma.
A man with a prolactin secreting pituitary carcinoma was treated by surgery and radiotherapy. Persistent hyperprolactinaemia partially responded to oral bromocriptine for four years. Serum prolactin then rose considerably with rapid, invasive tumour recurrence. Cytotoxic chemotherapy halted tumour progression for twelve months before fatal spread throughout the brain. Failure to normalise serum...

Correspondence to: Ioana Muntean, e-mail: [email protected] ABSTRACT. Hyperprolactinemia has different etiologic forms, among them, the prolactin-secreting pituitary tumors represent an important entity. In our study, were analyzed the clinical aspects, diagnostic procedures and therapeutical approach of 31 cases of prolactinomas (F/M ratio = 27/4) hospitalized in the Clinic of Endocrinol...
