Fig. 6. A 65-year-old woman with pyogenic abscess of the spleen.

A. Longitudinal ultrasonography (US) of the spleen shows a poorly defined round anechoic cystic mass (arrows) with echogenic internal debris suggestive of an abscess. Salmonella group D was identified by US-guided aspiration. B. Axial contrast-enhanced computed tomography image shows a rim-enhancing multiseptated hypodense lesion (arrows) in the spleen.
