A Large Meningioma Arising from the Right Anterior and Middle Cranial Fossae

[hermantheshocker]

The image shows a large meningioma arising from the right anterior and middle cranial fossae. A tumor of this size has a tremendous capacity to compress adjacent structures, and can even cause death by interfering with medullary functions. However, unlike rapidly growing, space occupying masses like acute hemorrhages (which often cause death), slow growing neoplasms are more readily tolerated as the neurologic tissues have time to accommodate them.

Meningiomas grow from the meninges as lobulated rubbery masses that can expand to quite large proportions. Since they grow steadily and slowly, they push on the adjacent brain and can irritate it, possibly leading to seizures or other symptoms. They have little malignant potential and as such, typically do not invade the surrounding parenchyma.

Additional images for illustration purposes.

Great post!

That poor person had to be in an unreal amount of pain.

That’s making MY damn head hurt. My dad had a massive stroke on 04/19/2021 with marked intracranial bleeding and his very first symptom was a severe headache. He has had a lifelong history of severe migraine disorder and he described a pain worse than any he has ever had........ and this man had kidney stones in the past (a.k.a. Feels like giving birth!!!).

No pain receptors exist inside the brain.

Right, but you will feel the pain from everything else, including the insane pressure.. the stabbing, throbbing, and sudden head pain. Eyes, and many other area can feel pain, just think of how things are connected.

I recently found out through a nech CT scan, then MRi, that I have a small meningioma right next to my spinal column. It's just barely nudging the column. We're keeping an eye on it. Another MRI in the summer to determine the growth rate.

Seeing this hits home hard but luckily, it's not at the same place.

Right. I don't feel anything so it doesn't give/gave me a clue that the mass was there. I just need to be aware on any changes on my balance, etc.

Great post. Shows how vascular these masses can be. Luckily benign and well circumscribed. Carcinogenic masses are usually in the brain tissue itself and are diffuse.
