What are the risks of operating the retinal detachment on a 2y.O. Who had a prior retinoblastoma, which is considered now cured?

Risks vs. rewards: The risks of surgery need to be weighed against the benefit of restoring or maintaining sight. If the chances of visual improvement are low, surgery may not be appropriate. If there is a chance of improvement in the long term, however, surgery would be appropriate. Please speak with your retinal surgeon and pediatric ophthalmologist; they should guide you in the right direction. ...Read more

What is the comparison of glioma and capillary tangelictasia ? How can they be confused?

What is the comparison of glioma and capillary tangelictasia ? How can they be confused?

Aggressive or high grade gliomas have many capillaries of their own and thus both lesions do have some something in common that shouldn't but may cause confusion ...Read more

What causes Glioblastoma in brainstem, & high grade glioma in brainstem in young adults?Thought brainstem had no glial cells to cause this in adults?

It's just bad luck: There are a few genetic syndromes that increase risk for glioblastoma / "high grade glioma", but beyond this it's simply a misfortune. All cancers arise from random mutations -- these are totally dumb luck. Anybody who told you that the brainstem has no glial cells is somebody you either misunderstood or simply shouldn't listen to. It's got a lot more glia than neurons like the rest of the brain. ...Read more
