Splenic abscess.
Fourteen cases of splenic abscess are reported and 159 cases previously cited in the literature are reviewed. The incidence, predisposing factors, pathogenesis, clinical features, bacteriology and radiologic findings are discussed. Infective endocarditis was the most common single antecedent infection. Hemoglobinopathies, non-penetrating abdominal trauma, and gastrointestinal malignancy appear to predispose the spleen to abscess formation. Emphasis is placed on clinical features and radiologic findings to aid practitioners in diagnosing this uncommon but often fatal infection. Also emphasized is the necessity for prompt surgical intervention when splenic abscess is suspected. An approach to the antimicrobial therapy in different clinical settings is outlined.
