Presentation
Mild cognitive impairment.
Patient Data
Anterior and contacting the basilar tip is a 6 x 10 x 7 mm (AP x ML x SI) nodule in contact with the floor of the third ventricle posterior to the pituitary stalk. Compared to white matter, the nodule is T1 isointense and T2/FLAIR hyperintense with no contrast enhancement.
Ventricular size and sulcal pattern demonstrate generalized cerebral involution. Supratentorial deep white matter and periventricular high T2 signal likely reflecting chronic small vessel ischemic disease.
Case Discussion
Incidentally found suprasellar mass, which has non-aggressive features and is favored to be a hypothalamic hamartoma. Comparison with prior imaging showed stability for over 8 years.
