Hi @alex3l and welcome to connect. That is a very interesting question.

Here is a research article that I think matchings your situation: "Intracranial Hemorrhage Sparing Meningioma in an Anticoagulated Patient" - https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1552-6569.2007.00111.x

Here is another discussion where others are talking about watching a meningioma tumor: https://connect.mayoclinic.org/discussion/watching-a-meningioma-brain-tumor/

Here is a discussion on atrial fibrillation that I thought would be helpful: https://connect.mayoclinic.org/discussion/side-efects/

Back to you @alex3l, how are you feeling?Any symptoms currently?

That does sound hard to have a meningioma and afib discovered all at once, @alex31. A lot to process at the same time. Since you were talking in your second post about following, or watching your meningioma, instead of immediately intervening, I moved your post here where you were posting before where others are talking about watching a meningioma.

Hoping that some other members here and from other discussions may know something about anticoagulant safety while you have a meningioma and whether it could prompt bleeding. @johnbishop may have some thoughts for you, as may @deblee @sanderjakidd @averagewoman @pegorr. They may also have had experience with the decrease in the sense of smell you are talking about.

Have you gotten a chance to talk to the pharmacist about your concerns related to the anticoagulant and the meningioma that was discovered, alex31? If so, what did he or she say?

My husband has atrial fibrillation but no meningioma. He had a stroke 3 years ago. He eventually found out it was because of a-fib. He is on xarelto and sotolol. Over the past 3 years we have learned a few things about a-fib. There is a strong correlation between sleep apnea and a-fib. My husband can’t drink more than one to two beers a day or he will go into a-fib. Stress while watching his favorite sports teams can cause him to a-fib. It took a while for us to figure this out. He has been stable for the past year with only one a-fib event. He has to be diligent about taking his medication at the same time every day. His medication was adjusted and changed a couple times to achieve success. He had a cardio version a couple times. My husband was extremely fortunate to have his stroke in his occipital lobe of his brain. He lost some peripheral vision at first but gained it back as his brain healed. I wish you luck on your health journey. This doesn’t answer your question about bleeding and your meningioma but it may be useful to prevent a-fib.
