Splenic abscess is an unusual disease and may be presented either as a localized area of infection in the spleen or as a part of generalized sepsis. Population-based autopsy studies have established the incidence of splenic abscess at between 0.2-0.7 per cent. An eleven-year retrospective study of cases of splenic abscess treated at Siriraj hospital, a total of 9 cases, is presented. Pseudomonas pseudomallei is the most frequent causative agent, found in one-third of the cases, especially if the patient is thalassemic or a resident in the Northeastern part of the country. Thalassemia is also the leading predisposing condition of this malady with the incidence of 33 per cent. There are some differences in the presenting clinical features in Thai patients compared with those reported in the literature. Splenectomy was performed in all but one who died of leukemia preoperatively. The mortality rate of this disease in this series is 11 per cent and we recommend splenectomy under antibiotic coverage as soon as the diagnosis of splenic abscess has been confirmed.

Splenic abscess is a rare clinical entity but may be underreported. A retrospective study at Srinagarind Hospital revealed 60 cases of splenic abscess between 1992 and 2001. The causative organisms were identified in 41 cases (68.3%). Gram negative bacilli were commonly isolated and Burkholderia pseudomallei was the most predominant. Diabetes mellitus and leukemia were common underlying diseases found in 46.3 per cent and 9.7 per cent of culture confirmed cases, respectively. The patients usually presented with fever, left upper quadrant pain, tenderness and splenomegaly. Multiple abscesses were more commonly found in the melioidosis than in the non-melioidosis group (p = 0.032), but a single abscess was more commonly found in the non-melioidosis than in the melioidosis group (p = 0.032). Concurrent liver abscesses, often multiple, were not different in both groups. Antimicrobials alone were given in 66.7 per cent of cases with melioidosis and 64.7 per cent of non-melioidosis group. Splenectomy and percutaneous aspiration were performed only in 29.3 per cent and 4.9 per cent of cases with splenic abscess. The overall mortality rate of splenic abscess was only 4.9 per cent in the present series. In conclusion, splenic abscess is not uncommon. Burkholderia pseudomalleli is the most common causative agent found in the present series. Therefore, it should be targeted in the initial empirical antibiotic therapy before the culture results are available especially when multiple lesions in the spleen and concurrent multiple liver abscesses are seen. Prolonged treatment with appropriate antimicrobials alone is usually effective. Splenectomy and/or aspiration may be useful in selected patients.

Splenic abscess is an unusual and potentially life-threatening disease. Due to the nonspecific clinical picture, it remains a diagnostic challenge. Splenic abscess should be suspected in febrile patients with left upper quadrant tenderness and leukocytosis, and diagnosis confirmed based mostly on imaging studies, microbiologic and / or pathologic evidence, or by response to antibiotic or antifungal treatment. We present 29 cases of splenic abscess treated in our hospital from 1990 to 2001. There were 18 male patients (62%) and 11 female patients (38%). Ages ranged from 4 to 85 years, with a median of 44 years. There were five pediatric patients (17%) and 24 adults (83%). The most common associated condition was leukemia. Most patients were immunocompromised (72%). The more common signs and symptoms were fever (90%), chills (41%), abdominal pain (31%), and leukocytosis (38%). Ultrasonography of the abdominal cavity was positive in 27 cases (93%); computerized tomography or magnetic resonance imaging was used in 26 patients (90%) and was positive in all patients. The abscess was solitary in 21 cases (72%) and multiple in eight cases (28%). Positive blood cultures were found in only seven patients (24%). According to the literature, the treatment of choice is still splenectomy, but in our study, the success rate of 75% with antibiotics alone indicates that antibiotic therapy should be considered an important alternative treatment modality in patients not suitable for percutaneous drainage and splenectomy.
