Hello. Thanks for asking from HCM.
I can understand you concern.
1. Replying your first question, most common complications of tumor surgery are mild like post-operative headache, ugly looking scar and
tingling sensation, collection of blood and fluid below scalp. They improve with time. Other important complications are intra-operative like bleeding,
injury of major vein or artery like
middle cerebral artery if tumor is reaching unto it. Due to anaesthesia drugs, patient may awaken late or may need ventilatory support, fluid overload, sodium imbalance. In post-operative period, patient may develop seizures,
brain swelling and herniation which may need decompressive surgery, sodium imbalance, memory impairment. Long term complication includes recurrence of tumor if partial removal only and seizures. These major complications are less than 10-15%.
2. According to the MRI report, tumor is located in right
temporal lobe which is a bad location. Tumor size is 39 X 53mm which is significant. This much size tumor in temporal lobe can cause tentorial herniation which is dangerous for life. So your daughter needs surgical decompression of tumor.
Good news is DNET. It is a grade I tumor. Complete removal means 100% tumor free life in future. Chances of
brain edema due to tumor is very less as compared to other brain tumors.
3.
Hydrocephalus surgery is not an contraindication for surgery. After suture removal, you can get surgery done.
I did not get your MRI film or report. If you are still having doubts, you can ask premium question and send MRI reports. HCM will forward your reports.
Thanks. Hope it will help you. Take care.
