When do you consider lumbar spinal fluid drainage after acute spinal cord injury?
Extremely rarely indicated.
Do you take any special precautions when treating cervical spine metastases?
For each spine met case, it's important to determine whether it's a surgical or radiotherapy case. Spinal instability neoplastic score (SINS) and Bilsky grade (epidural cord compression) are two important parameters to consider. If SINS is 6 or below and if Bilsky grade is 1c or below, surgical inte...
What is your approach to management and surveillance in low grade traumatic blunt ICA injury?
For blunt cerebrovascular injury (BCVI), I use the Biffl scale to evaluate the extent of vessel trauma. The extracranial neck vessels, such as the cervical ICA or VA, are most commonly affected. The Biffl classification consists of five categories, with Grade 1 representing a low-grade injury. This ...
How do you distinguish between episodes of vascular steal and seizures in patients with an AVM?
Distinguishing between vascular steal and seizures in patients with AVMs can be challenging, but certain patterns may help. Vascular steal occurs when blood is shunted through the AVM nidus, bypassing the surrounding tissue and causing regional or global oligemia. The shunting can result in transien...
For patients that fail initial SRS for trigeminal neuralgia, what factors do you consider when considering re-irradiation?
Failure within 6 months/No response: Is vascular compression present? Yes = Consider Microvascular decompression. If contraindicated repeat SRS to 50 Gy. No + then was the nerve clearly visualized on MRI? Yes = Possible repeat SRS to 50 Gy. No = then that could be a cause for failure, consider ret...
Do you treat bilateral trigeminal neuralgia with SRS?
Yes, but I treat the side with more severe symptoms first and treat the other side 6 months later. I do not make dose modifications. I have treated some patients with bilateral trigeminal neuralgia in this fashion with no issues.
How would you manage a new suspected brain metastasis in a patient with a distant cancer history?
So I think there are some details missing but generally, if there is a suspected brain metastases in a patient with distance cancer history and that biopsy/resection is not feasible, I would consider additional workup including extracranial imaging. If the suspected brain metastases is asymptomatic ...
Would you offer adjuvant radiation therapy in a young adult with NF1 who has a craniopharyngioma s/p STR?
In NF1 patients, radiation therapy for craniopharyngioma has been associated with vascular damage and Moya Moya syndrome. On the other hand, subtotally resected craniopharyngiomas have a high chance of recurrence. It has been shown that, dosimetrically, intensity-modulated proton therapy (IMPT) coul...
How do you approach anti-seizure medication management when it was started by another team for a seizure-naive patient before/after craniotomy for a tumor?
I would refer you to Dr. @Dr. First Last's answer to a similar question (https://www.themednet.org/question/15031) which beautifully summarizes data and guidelines. I usually counsel patients that everyone regardless of their medical history has a certain risk of seizure under physical stressors, th...
What is your approach to monitoring the neurologic status of a patient with a traumatic brain injury requiring burst suppression for status epilepticus?
As with any other patient in status epilepticus requiring burst suppression, the neurological exam becomes limited to pupillary light reactivity. Pharmacotherapy used in the management of status epilepticus does not negate pupillary response. Not being able to obtain frequent neurological exams on a...
