There is slight interval decrease in size of the pineal tumor, which measures 15 RL x 18 SI x 28 AP mm, previously 17 RL x 23 SI x 29 AP mm. There is a right transfrontal ventricular catheter that terminates in the basal cisterns. There is no longer dilatation of the third and lateral ventricles. There is no evidence of acute infarct or hemorrhage. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable.
1. Interval slight decrease in size of the size of the residual pineocytoma.2. Interval decrease in size of the shunted ventricular system.
