Does anyone know the disease they are talking about? I was thinking lupus which makes sense with the answer, but i can’t find anything on anterior chamber of eye and choroid plexus.

liverdietrying  It's lupus, all the symptoms listed are classic especially the serositis. Anterior chamber of the eye = uveitis. Choroid plexus = cerebritis. For a great overview, check out this (free) video: +1  
in_a_pass_life  I think this was reactive arthritis, not lupus. Choroid plexus not just in the brain, also in eye (can’t see, can’t pee, can’t climb a tree). Mechanism of reactive arthritis is immune complex deposition, per UWorld, which was correct answer. +2  
trichotillomaniac  The inside of the eye is divided into two chambers: the anterior chamber and the posterior chamber. Both chambers contain fluid, and when there’s inflammation in the eye, a specialist can often see inflammatory cells in the fluid. +  
trichotillomaniac  I agree that this is Lupus after doing some more research! +  
nwinkelmann  I find this article describing the SLE ocular manifestations, including uveitis and cerebritis. Also this talks about the lupus cerebritis (choroid plexus inflammation): +  
medulla  every time I read about Lupus there is something new!! +

This was SLE.

Think: 1,2,3= S-L-E

Using ACID: Type III is for Immune Complexes
