I cannot speak for the other lawyers who turned down this case. Medical malpractice cases are expensive, time consuming, and usually very difficult. I can see several issue with the case. One issue is whther the doctor's failure to see the tumor initially was a substantial factor in causing your brother's ultimate injuries. In other words, the doctor's lawyer will probably argue that the tumor was there. Removing the tumor was going to cause damage, even if the doctor caught it 41 days earlier.
This is just one of the difficulties.
With that said, I urge you to continue to try to find a lawyer to help you. This sounds like a terrible situation and I encourage you not to give up. Good luck.
I'm very sorry for your loss.
I agree with the other response. It's expensive to prove a medical malpractice case, and despite what doctors would like you to believe, they win most cases that have to go to trial. Did you get both MRI films? You might get them both and engage the services of an expert radiologist to review them for you - you can find an expert witness/radiologist online. Perhaps if you do some of the leg work yourself, you can position it for a successful litigation - or at least obtain the answers that you and your family need about whether your brother's death could have been avoided.
Why did it take 41 day to provide the MRI results? At the very least, you should consider reporting this to the Board of Medical Examiners.
This response does not constitute legal advice and does not create an attorney-client relationship. Due to the complexity and ever-changing nature of the law and to the limitations of this forum, this information may not be adequate for your specific situation.
Could be a difficult case to prove, thus, I would recommend that you offer to pay the lawyers' up-front costs so they won't be out-of-pocket investigating this claim.
No one can speculate why the attorneys turned the case down. Without knowing what the first MRI showed that is one issue. if it were positive for some problem, that would make it a better case. Then you have a 41 delay before the brain bleed. The only way to know whether you have a case is to have records and imaging studies reviewed. Stroke cases can be difficult. Just not informing you of results, may be bad or poor practice, but unless the first MRI showed a problem, it may not have showed anything in which it is very difficult to link up headaches 40 plus days earlier with a stroke.
