Best Post of April 2013: A Rich Focus
The next in our "Best of the Month" series is a post from April 16, 2013.
A Rich focus is a tuberculoma in the cerebral cortex. Rich foci become
particularly significant when they rupture into the subarachnoid space
and cause tuberculous meningitis. This entity is named for Johns Hopkins
pathologist Dr. Arnold Rice Rich (1893-1968), who first described it.
