Splenic infarction in endocarditis: case report]

Splenic infarction is a very rare event though it can occur in a multitude of conditions with general or local manifestations. Splenic involvement in infectious endocarditis can be either infarction or abscess formation. The clinical picture is usually nonspecific and the diagnosis is often not initially suspected. We present a case of a 67 year-old male patient with infectious endocarditis who has been diagnosed with a splenic infarction by abdominal CT scan. The infarction was a result of septic embolization from the infected endocardium. The patient was initially managed conservatively with triple antibiotic therapy and regular follow-up ultrasound scan. The persistence of abdominal symptoms and the suspicion of splenic abscess formation led to the decision of performing splenectomy. Although imaging can characterize the nature of a splenic lesion, it is sometimes impossible to differentiate between infarction and abscess without histopathological confirmation. Splenic infarction should be suspected in all patients with a past history of thromboembolic disease who complain of left upper quadrant pain and present with localized or systemic inflammatory signs. Unfavorable clinical course and suspicion of abscess formation are indications for surgery. The characteristic features of splenic infarction are discussed together with a review of the recent literature.
