[Radiological investigation of prolactin-producing pituitary microadenomas (author's transl)].
The CT scans and thin section sellar tomograms of 12 patients with amenorrhea, galactorrhea and hyperprolactinemia syndrome were analyzed. Three patients showed a remodeled sella on plain X-ray of the skull and a protrusion of the suprasellar cistern below the diaphragmatic line on pneumoencephalography (empty sella). CT scan confirmed the low absorption values within the sella and showed an intrasellar area of increased density after contrast infusion. In 9 patients, thin section tomograms showed an abnormal sellar configuration. 5 of these patients had an eccentric, high density area adjacent to the sellar floor on postcontrast CT scans. The remaining 4 patients did not show postcontrast enhancement.
