History of craniopharyngioma and progressive cysts. Status post partial resection of cyst drainage on March 30, 2013. Status post Pegintron and radiation therapy. Allowing for differences in angulation and slice selection, there is overall slight decrease in the size of the peripheral cystic component of the complex suprasellar mass. The central solid part has not changed. For example, the cystic component indenting the undersurface of the right frontal lobe now measures 12 mm compared to 16 mm previously. A similar component deforming the right cerebral peduncle now measures 12 mm compared to 14 mm previously. The component involving the right ambient cistern now measures 19 mm x 13 mm compared to 20 mm x 16 mm previously and now displays more CSF-like intensity. There continues to be involvement of the prepontine, cerebellopontine angle cistern, right ambient and right quadrigeminal cisterns, as well as the right middle cranial fossa, with associated mass effect upon the brainstem, right medial temporal lobe, and hypothalamus-optic apparatus complex. 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. The basilar artery is tortuous and encased by the mixed cystic and solid mass. There are postoperative findings related to right temporal craniotomy and stable position of right frontal approach drainage catheter with the tip in the right prepontine cyst. The ventricular system also appears to be unchanged. There are foci of susceptibility effect within the right temporal lobe resection cavity, consistent with hemosiderin deposition, and within portions of the tumor, which likely represent calcifications.
1.Further, slight regression in the peripheral cystic component of the complex suprasellar craniopharyngioma. The tumor has extensive involvement of the adjacent structures as described previously.2.Other postoperative/treatment findings are not significantly changed.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
