Initial follow-up CT scan 2 months after treatment with percutaneous drainage showing a marked decrease in size of the abscess (thick white arrow; a), however, Osteolytic bone lesion in adjacent second lumbar vertebra (small white arrows a and b), a streaky densification of the pericaval connective tissue and a nearly complete thrombotic occlusion of the infrarenal inferior vena cava (white arrowhead c)), which was probably infected (small gas bubbles). Infection related air bubbles in the retroperitoneal space can also be seen now along the aorta to below the aortic bifurcation
