An uncommon cause of recurrent strokes: Tropheryma whippelii endocarditis.

BACKGROUND Cardiac involvement in Whipple's disease is not an uncommon phenomenon in autopsies, but its clinical occurrence is often overshadowed by gastrointestinal symptoms. We report a very atypical manifestation of this disorder. SUMMARY OF REPORT An extraordinary presentation of an extremely long-lasting, culture-negative endocarditis caused by Tropheryma whippelii is described, the clinical consequence of which has become apparent in recurrent strokes. CONCLUSIONS Cardiac involvement of Whipple's disease should always be considered in culture and serologically negative endocarditis. The polymerase chain reaction technique may be a useful tool to confirm a presumed diagnosis of T whippelii endocarditis and consequently to apply an effective treatment regimen.
