Fig. 1.

Abdominal CT-scan (a) showed a heterogeneous fluid filled mass in the right hepatic lobe, with thickened internal septations and partial thickening of the outer wall (green arrows). The mass measured approximately 7.3 × 5.3 × 4.6 cm³. The largest pocket of fluid measured approximately 6.1 × 3.3 cm². Percutaneous drainage of the mass confirmed it to be a pyogenic liver abscess due to Klebsiella pneumoniae. After drainage of the abscess and treatment with intravenous antibiotics, (b) the abscess cavity abutting the diaphragm was almost completely cleared (green arrows), as shown with the drain in place (red arrows)
