Abstract
During a recent 5-year period, 12 patients with splenic abscesses were evaluated by abdominal ultrasound (US) examination. Multifocal abscesses were noted in seven patients, three of them were secondary to infectious endocarditis, three were in immunosuppressed state, and one was caused by tuberculosis. The latter four patients had developed splenic microabscesses with a diameter of 4 cm). Simple aspiration in conjunction with antibiotic administration was done for seven smaller abscesses (diameter <3.5 cm) in five patients. A second drainage, either for a dislodged catheter or a recurrent abscess, was performed in two cases. All patients had uneventful clinical course following this therapeutic approach.
