He had been receiving weekly steroids with some improvement, but was now getting more symptoms of encephalopathy (confusion, weakness, etc.). A brain biopsy was performed, which showed the small vessels stuffed with neoplastic B-cell lymphocytes. The diagnosis based on brain biopsy was intravascular (angiotrophic) large B-cell lymphoma, a rare lymphoma wherein the neoplastic cells lack the capacity for diapedesis, remaining captured within the vascular lumen (pictured) and causing secondary brain infarction.

A 48-year-old man with mental confusion
We had an interesting case here last week of a 48-year-old gentleman with a clinical diagnosis of exacerbation of "some kind of an autoimmune encephalitis". The clinicians were wondering abo

So is he going to be OK?
Don't know yet. Probably not. I will keep you updated.
He is stable now. Consulting hem-onc. Rituximab is a promising treatment, but this patient has hepatitis C, so has risk of flare up.
Thanks for the update, Brajesh. Please keep us informed about the patient's course.
As soon as I saw the photo, I knew the diagnosis. Piece o' cake!

Yes, it is an easy diagnosis from a surgical pathology point of view. But the neurologists were scratching their heads for a long time regarding this case. Could it be primary CNS angiitis? MS? They were perplexed until a biopsy was performed.

Yes, it can be hard from a clinical standpoint (which I know from my days as a neurologist).
Its been a long time since I have seen such a clear image. Its always such a shame when what I would consider quite a 'young' person is affected.
