Splenic abscesses: Reports of two cases with review of the literature

Abscess of the spleen is a rare discovery, with about 600 cases reported in the international literature so far. It is more common in the presence of infection at different primary sites, especially endocarditis or in cases of ischemic infarcts that are secondarily infected. Immunosuppression and trauma are well-known risk factors. Recently, intravenous drug abusers and alcoholics have shown an increased incidence compared to other high-risk groups. However, encountering this entity in general population is uncommon. Clinical examination and laboratory findings are not constant; thus, imaging is a necessary tool for establishing the diagnosis, with a choice between ultrasound and computed tomography. If untreated, the mortality reaches almost 100%. Treatment includes conservative measures and surgical interventions. Splenectomy has been the preferred approach in most centers. More recent studies have suggested the use of advanced and alternative options, including laparoscopic surgical and percutaneous interventions. Changing trends, in view of the importance of immunological role of spleen, have emphasized more on spleen preserving protocols, especially in children and young patients, and in cases of solitary abscess with a thick wall. conducted a literature review by analysis of various high-risk groups, presentation, diagnosis and treatment of splenic abscess, and have presented here a report of two cases.
