 There are post-treatment findings, including a defect in the right lateral temporal lobe. There is interval evolution of the signal characteristics of some of the cystic components of the craniopharyngioma, without significant interval change in the overall size of the tumor, which spans the sella, suprasellar cistern, and other adjacent cisterns, and measures up to approximately 45 mm. The basilar artery is tortuous and encased by the tumor and there is persistent mild mass effect upon the surrounding brain and brainstem. There is asymmetric volume loss of the left cerebellar hemisphere associated with increased T2 signal, which may be attributable to crossed cerebellar diaschisis versus chronic ischemic effects. There is a right transfrontal catheter with the tip in the right prepontine cistern. The ventricular system appears to be unchanged in size. The skull and orbits appear unchanged.
Post-treatment findings related to a complex craniopharyngioma, without significant interval change in size of the tumor or the shunted ventricular system.
