A computed tomography scan of the chest showed a large Austrian’s triad, a rare complication of disseminated Strepto- pericardial effusion with signs of cardiac tamponade, a right coccus pneumoniae infection consisting of pneumonia, menin- lower lobe infiltrate, and a small right pleural effusion gitis, and endocarditis, is a clinical reminder of the virulent (Figure 2).

In 1964 Aus- trian and Gold published a review of 529 cases of pneumo- coccal bacteremia with no identified cases of pericarditis.3 A 30-year literature review of pneumococcal endocarditis in the penicillin era by Aronin et al., covering the period 1966— 1996, identified a total of 197 adult cases. No cases of concomitant clinical pericarditis were noted, although four of 38 (10.5%) patients undergoing echocardiography had pericardial effusions.4 Taylor and Sanders reviewed the clin- ical spectrum of 2064 reported cases of non-meningitic invasive pneumococcal disease encompassing 30 years of published literature (1966—1997). They identified 70 isolated cases of pericarditis and five of cardiac tamponade.5 In the period 1980—1998 only 15 cases of pneumococcal pericarditis were reported in the literature.6 The concurrence of bacteremic pneumococcal pneumonia, meningitis, and endocarditis is a rare and virulent presentation of invasive pneumococcal disease, first described by Osler and Figure 2 Admission computed tomography of the chest. later described and published by Austrian, for whom the Austrian’s triad with complications e25 syndrome is named.7 Austrian’s syndrome remains rarely References reported in the literature.
