Haemophilus aphrophilus associated spleen abscess: an unusual presentation of subacute endocarditis.

Tien YC, Chang CC, Liu YM - J Clin Med Res (2012)

Bottom Line: Abdominal computed tomography (CT) indicated a 1.6 cm abscess in the spleen.We diagnosed the patient with subacute endocarditis complicated with spleen abscess.The patient recovered fully after two weeks antibiotic (Ceftriaxone) treatment.

ABSTRACT
The HACEK group of bacteria (Haemophilus spp., Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, Kingella spp.), is uncommon pathogens of infective endocarditis, but can cause life-threatening events such as heart failure or formation of lethal emboli. Here we report a 58-year-old Asian man with a past history of congenital valvular heart disease who presented with sudden onset of left flank pain followed by fever with chills for 2 weeks. Abdominal computed tomography (CT) indicated a 1.6 cm abscess in the spleen. Culturing indicated the presence of Haemophilus aphrophilus. We diagnosed the patient with subacute endocarditis complicated with spleen abscess. The patient recovered fully after two weeks antibiotic (Ceftriaxone) treatment. Clinicians should give further attention to infective endocarditis caused by bacteria in the HACEK group in patients with metastatic infection such as spleen abscess with suspected valvular heart disease.

Figure 1: Abdominal CT indicating a nodular lesion at the spleen (point by white arrow) that was 1.6 cm in diameter and showed mild enhancement in a post-contrast study, indicative of a spleen abscess or infarction.

Mentions: Abdominal computed tomography (CT) was performed on suspicion that the fever and left flank pain were related to an abdominal infection. This CT indicated a 1.6 cm nodule lesion in the spleen (Fig. 1), compatible with site of tenderness, suggestive of spleen abscess or infarction. Empiric therapy with ceftriaxone 2 g every 12 hour was prescribed initially.
