[Hematogenous meningitis caused by Staphylococcus aureus with sacro-iliitis and multiple abscesses. An infrequent association].
BACKGROUND
Meningitis due to Staphylococcus aureus (MSA) is an uncommon infectious condition. It forms from 1-9% of all cases of bacterial meningitis, and is characterized by a high morbidity and mortality. Ever since the first publications dealing with this type of meningitis, two basic mechanism have been described for the development of this infection: post-neurosurgical and hematogenous, also known as spontaneous.


METHODS
Our objective is to present the case of a 65 year old woman who developed hematogenous Staphylococcus aureus meningitis, without any predisposing factors. During clinical investigation, the meningeal infection was seen to be associated with septic arthritis of the right sacro-iliac joint (shown on isotope studies) and with retro-peritoneal and gluteal abscesses (shown on computerized tomography). In this patient the pathological findings were: MSA, retroperitoneal and gluteal abscesses, and unilateral sacro-ileitis. To date such a combination has not been described (Medline search from January 1982 up to june 1996).


CONCLUSIONS
After analysis of the pathogenic findings of the MSA directly involved in this case we conclude by emphasizing the following points: 1. It is very important to make a thorough search for a primary infectious focus responsible for MSA, completing the physical examination of the patient with imaging techniques (conventional radiology, CT, isotope studies, etc.). 2. Depending on the primary focus found in an MSA, antibiotic treatment may sometimes have to be complemented by other methods of treatment to avoid subsequent complications.
