What are the principal findings?
Abnormal contrast enhancement within the hypophyseal stalk, tuber cinereum and midline portion of hypo-thalamus as well as the subependymal portions of the third ventricle, particularly on the left. Faint parenchymal enhancement.
MRI of the pituitary and brain demonstrates abnormal contrast enhancement within the hypophyseal stalk, tuber cinereum and midline portion of hypothalamus as well as the subependymal portions of the third ventricle, particularly on the left. Contrast enhancement of soft tissue within the third ventricle at the level of the foramina of Monro appears more prolific than expected, suggesting the process may have also extended to this region with nodular enhancement also seen along veins running along the posterior aspect of the third ventricle. Faint parenchymal enhancement is also noted, particularly in the right parietal lobe. The delayed sagittal images appear to show more vivid contrast enhancement of the capsule of the pituitary.
