 There is no evidence of recurrent tumor. There are unchanged postoperative findings related to previous right frontal craniotomy with encephalomalacia along the surgical tract and expected dilatation of the atrium of right lateral ventricle. There is interval decreased ventricular caliber most prominent in the lateral ventricles and the third ventricle. There is unchanged linear bifrontal encephalomalacia (right greater than left) associated with old bifrontal shunt catheters. There is unchanged cystic encephalomalacia in the right basal ganglia. There are scattered T2 hyperintensities in the periventricular and subcortical white matter which are nonspecific.There is a new 5 mm cystic space immediately adjacent to the left lateral ventricle atrium which is nonspecific and does not enhance.There is no acute infarct, mass effect or midline shift.
1.Decreased ventriculomegaly with no evidence of recurrent tumor.2.New nonenhancing nonspecific 5 mm cystic space adjacent to the atrium of the left lateral ventricle. Recommend continued attention on follow-up exams.
