Having pus in your brain is a problem no matter how you cut it, but finding it in there can be a challenge.  While the classic triad is usually fever, headache and a focal neuro deficit, this isn’t always present.  Dave Traficante (@davetraf) just published a pretty cool case of bifrontal brain abscesses in the International Journal of Emergency Medicine of a gentlemen with this very problem.  Interestingly, he didn’t have any focal neuro deficits, but he did have a very flat affect and could care less of the pus accumulating in his brain which coincided with the frontal lobe location of his abscesses.
