Craniopharyngioma surveillance. There has been interval evolution of postoperative findings related to right frontal craniotomy, with resolution of extra-axial fluid deep to the craniotomy flap. There is interval increase in size of the heterogeneously enhancing suprasellar mass, attributable to enlargement of a cystic component posteriorly. The signal characteristic of other cystic components have also changed and some of the cysts are slightly smaller. Overall, the tumor measures up to 42 mm in the anteroposterior dimension, previously 39 mm. There is increased mass effect upon the surrounding brain parenchyma and interval increase in size of the bilateral lateral ventricles and superior portion of the third ventricle. There is persistent marked mass effect upon the optic apparatus and circle of Willis vessels, as well as high T2 signal along the left optic tract. There is no evidence of acute infarct. There is no midline shift or herniation. The orbits are grossly unremarkable.
Interval increase in size of the suprasellar craniopharyngioma, attributable to enlargement of a cystic component posteriorly, with resultant aggravation of obstructive hydrocephalus.
