Female, 54 years old, with craniopharyngioma, presenting with vision loss, preoperative planning for tumor resection. A cystic and solid, partially enhancing suprasellar mass is redemonstrated measuring 43 x 31 mm in the axial plane. This compares to 37 x 27 mm on the prior MRI. Interval increase in size represents growth of both the cystic and solid components.This lesion fills the suprasellar cistern from the level of the sella to the floor of the third ventricle into which it protrudes. The optic apparatus is markedly displaced by this process. The cerebral peduncles are splayed.Redemonstrated is evidence of a right fronto-parieto-temporal craniotomy. Encephalomalacia of a small part of the right frontal lobe is unchanged.No new lesions are seen. No abnormal extra axial fluid collections are detected. The ventricular system remains within normal limits for size and morphology. A developmental venous anomaly is noted incidentally within the pons.
