1) Chronic brucellar hepatosplenic abscesses (brucellomas) are rare (about 2% of cases), being considered true focal complications.
In summary, (I) brucellosis may initiate demyelinating process like as seen in the 1st, 2nd, and 8th cases; (II) brucellar meningitis may be the only sign of brucellosis, as in 9th case or it may be first sign of brucellosis as in 10th case; (III) the complication may be silent, part of systemic brucellosis as in 13th, 16th, and 18th cases, and it may be overlooked; (IV) it also may be confused with tuberculous meningitis as the 11th and 12th cases; (V) during the first weeks of the disease, specific immune response may be delayed in serum and/or CSF like as observed in the 10th, 12th, and 17th cases; therefore, serologic tests should be repeated weekly, particularly in endemic regions.
