Imaging brain tumors - 2 - Astrocytomas

[@bobbyewing311]

6:23 my brother's CT looked EXACTLY like that. I remember the doctor pointing with his pen and making markings on the films (this was 2001 so digital radiography wasn't common back then) and showing the splinters that went out from the tumor invading other parts of the brain and he was like "we could remove this tumor and all the spikes but there will always be something growing back because they could never get 100% of them. He had Grade 4 astrocytoma and passed away 3 years after diagnosis. In that time he was able to tour the country with his band, he got to go on trips and meet many famous and important people... He always walked with God and always told me he wasn't afraid of dying. Prayers for ALL affected by cancer.

[@LearnNeuroradiology]

I'm sorry to hear that. Sadly, these tumors are very tricky to deal with because they blend into the normal brain around them. I'm glad your brother was able to have good experiences after his diagnosis, and we keep working to make treatments work better! Thanks for watching the video.

@@LearnNeuroradiology He went through so many crazy surgeries and every single time the doctors would sit my mom down and go over the risks and the benefits and they always would get the tumors out and they would not cause any damage in the surgery or the followup care. I mean he had a part of his skull removed and then they put a metal plate in there and then the plate got infected so they took the plate out and for a year and a half he had a literal hole in his head. I remember one time the worker at Walmart wouldn't let him use the mobility cart (he probably saw 2 teenagers and through we were messing with it) and he didn't want any trouble and he just stood there while the guard was telling him to move and I took the beanie off my brother's head and watched his jaw hit the floor, needless to say that guy learned a valuable lesson. But I digress. Shout out to Dr. Abdoula Farrukh who carried a picture of my brother with him and he performed so many crazy feats one might say he was a miracle worker but his skill as a surgeon gave me and my family a lot of quality time that we otherwise wouldn't have and for that I think of my case as a blessing rather than a tragedy because I know of some people who get diagnosed and are not so fortunate and have terrible quality of life in the few short weeks/months they do survive.

Can chemotherapy shrink the tumor? Is there any chance to undergo for grade4

Hello doctor, my question can MRI report scan wrong or missed like CT Scan blurred images? I'm already MRI with contrast injection. I don't know why I have smell senses seizures after 9 years life without seizures, I have Astrocytoma grade 2 history in 2011 and this problem are done with operation and radiation 32 times with Tomotherapy. In my last MRI scan in March 2020 are clear but in MRI report said no tumour but seems Gliosis Post Op and Atrophy Parahippocampal in lobe temporal right side. I already consult with two doctor but the doctor said I am just epilepsy, meanwhile seizures drug are not make the seizure go away. The MRI result is that normal without any problem?

[@LearnNeuroradiology]

This is a little bit of a complex question. I think you should probably discuss this with your doctors. If necessary, they can ask the radiologists specific questions about what they think.

I had a grade 2 Astroytoma, I had surgery and 100% was removed, if it were to return would it most likely to be grade 3?

[@LearnNeuroradiology]

Not always. Sometimes grade 2 tumors come back as grade 2 tumors again. You can sometimes tell on imaging because they look the same as they did before they were removed. Sometimes they come back as a higher grade, such as grade 3 or grade 4. Imaging might look worse, like more enhancement or faster growth. Glad you had a good recovery after surgery and best of luck in the future.

Hi, regarding the CT taking in case 2; how do you differentiate it from the ischemia of brain CT (with loss of grey-white differentiation, may cause midline shift (due to edema?) Thank you for a good and helpful video

[@LearnNeuroradiology]

That's a great question. You cannot always tell. Hemorrhage and infarcts can be tremendous mimics of tumors because they can also get mass effect. Your best bet is to try to differentiate if they have vasogenic edema (like a tumor) or cytotoxic edema (stroke). Vasogenic edema (tumor) often spares the adjacent cortex, whereas a stroke will have a wedge shape all the way to the cortex. In this case, if you look closely at the CT (around 2:55), it looks like the insula is spared along the lateral side of the mass. This is confirmed on the MRI (3:08 and 3:36), where you can see a thin rim of normal, but compressed cortex along the right side of the mass. There is also a little bit more mass effect than you usually see with an infarct, but that is not perfect. Either way, it can be hard sometimes, and you can be fooled. In most situations, the patients are going to get an MRI anyway and you can see the difference. If a patient can't get an MRI, or you don't have one, you could get a short-term follow up. An infarct or hemorrhage will change pretty quickly, but a tumor will not.

[@LearnNeuroradiology]

Hi Henry. First, I'm sorry to hear that your family member has an anaplastic astrocytoma. It can definitely be hard to hear about this, and hopefully you have a supportive medical team and family members who can help you through this. Anaplastic astrocytomas have a life expectancy of years, not months or weeks. It depends a lot on the location, genetics of the tumor, and treatment (whether it is resected, treated with radiation). You can talk to your doctor more about what the expected course is and they should be able to tell you more.

[@aygunhuseynova9681]

low grade astrocytoma is a benign or bad-tempered?

[@LearnNeuroradiology]

When most people say low-grade astrocytoma, they mean grade 2 diffuse astrocytoma. They are malignant tumors (bad-tempered) that usually return even after surgery. Some other tumors are well circumscribed and surgery is generally curative (or at least a high probability of cure), like pilocytic astroctyoma (WHO grade 1)

[@LearnNeuroradiology]

@@HVLib I'm sorry to hear that you have a tumor. Unfortunately, grade 2 tumors are not entirely benign in that they will often come back. However, there are some very effective treatments including surgery and radiation. You should talk to your doctor about the chances of your own tumor coming back and how to best follow up.

Hi. I just got diagnosed with an astrocytoma in my right temporal lobe, main symptom being seizures. I dont really know any other details other than it is 8 by 11 centimeters and I am getting follow ups from duke, UVA, and Johns hopkins. If you had to guess, would you think malignant or benign?

[@LearnNeuroradiology]

Hi Delaney, I'm sorry to hear that you got diagnosed with a tumor. I can't tell without more information how benign or malignant it may be. Astrocytomas range all the way from grade 1 (the best outcomes) to grade 4 (the worst outcomes), and yours could be anywhere in between. The good news it it sounds like you have a team of doctors from great places that is helping you out. You can ask them any questions you have, including what grade the tumor is and what the outcomes are like. I wish you the best of luck in dealing with the tumor though. It's a tough diagnosis but hang in there! LNR

[@LearnNeuroradiology]

I'm sorry to hear about your family member. These tumors are very challenging to deal with because they infiltrate into the brain next to them. You can't remove them without taking out too much normal brain. That's why most of the time they need radiation and chemotherapy as well. Even then, they often come back. Right now, the best solution we have is to get repeat MRIs to see if the tumor has come back and then make a new plan to do new more surgery or radiation. Best of luck to you and your family though.

I'm sorry to hear that your family member has a brain tumor. There is a pretty big difference between a pineal tumor and an astrocytoma in terms of what the prognosis is. They may not know the diagnosis without taking a biopsy first, then they should be able to tell you more about the proper treatments and prognosis. I'd encourage you to have this discussion with his/her doctor as you all decide upon a treatment course.

No it's not just you, his voice is rather deep, and with as close as he was to the mic during recording it made it sound kinda like lots of clicks and grunts/grumbles. Had he backed away from the mic, and spoken louder it most likely would have been easier to understand and make out what he is saying. Also everyone is different, some people have a hard time hearing low frequency, or deep sounds, but are then able to hear high pitched, or high frequency sounds extremely well. Then there are those who can't hardly hear high pitched/frequency sounds, but can very easily hear low frequency or deep sounds extremely well. My mother is the type who falls into the latter category of not hearing high pitched/frequency sounds, but can hear low frequency or deep sounds extremely well. So I always have to turn the base down in my vehicle when she rides with me, or it bothers her. I am the exact opposite and hear high pitched/frequency sounds well, but not the low or deep, which is why I like to turn up my base, and turn down my treble.

My sister has been diagnosed with Astrocytoma grade 3. She has lost feeling in her legs and can’t get around. The medical team can’t remove the tumor because it’s on both sides of her brain.

I'm sorry to hear that. It sounds like it has been a bit of a struggle. Many of these tumors are not resectable and require a combination of treatments, including surgery, radiation, and chemotherapy. Unfortunately, most of them are not completely curable although they can sometimes be kept under control for months to years. Sometimes parts of the tumor get better while other parts may bet worse. I think the best thing to do is discuss your concerns with her doctors to see what can be done and to see if a new therapy or a change in therapy is warranted. Hopefully they can help you with these concerns. Good luck!
