Female, 10 years old, with sellar mass. Presurgical planning exam. A large mixed cystic and solid, inhomogeneously enhancing mass is evident involving the sella and suprasellar cistern. Areas of low T2 signal within the lesion and around the periphery of the lesion likely reflect calcifications noted on outside CT. The lesion abuts and may slightly narrow the ICAs, but the major intracranial vascular flow voids are preserved. The lesion splays the optic apparatus and cerebral peduncles. The lesion invaginates into the region of the third ventricle which is deformed as a result. The lateral ventricles and fourth ventricle are normal in size. Crescentic T2 hyperintensity is seen within the left basal ganglia. Incidentally noted is a developmental venous anomaly which traverses the left cerebral hemisphere.
Large cystic and solid inhomogeneously enhancing mass involving the sella and suprasellar cistern.The lesion exerts significant mass effect upon the optic apparatus and cerebral peduncles.Curvilinear T2 hyperintensity within the left basal ganglia could represent edema or an ischemic lesion.
