Pineal parenchymal tumor. There has been interval laser ablation of the pineal region mass with increase non-enhancement centrally, but no significant change in size, measuring approximately up to 40 mm. There is a small amount of intraventricular hemorrhage. A right frontal approach ventriculostomy catheter extending into the anterior horn of the right lateral ventricle. There is no significant change in size of the ventricular system. There is mild diffuse dural enhancement. There is a small varix in the left orbital apex. There is an unchanged left occipital scalp nodule.
1. Interval laser ablation of the pineal region mass with resultant increased central necrosis, but no significant change in size.2. Small amount of intraventricular hemorrhage. 3. No significant change in size of the shunted ventricular system.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
