Multidetector row CT incidentally identified a gas-containing filling defect in the right atrium indicative of a thrombus infected by Klebsiella pneumoniae in a patient with end-stage renal failure.
Case Report (n=1)
Multidetector row CT can incidentally identify gas-containing infected right atrial thrombi in patients with dialysis catheters and septicaemia.

May alert clinicians to infected right atrial thrombi on CT in septic dialysis patients; hypothesis-generating and requires prospective validation.
Right atrial thrombus formation is a known complication of dialysis catheter placements. We describe the case of a 61-year-old woman with end-stage renal failure who presented with gram-negative septicaemia. A gas-containing filling defect was noted incidentally in the right atrium during a CT scan of the abdomen and pelvis, indicative of a thrombus infected by a gas-forming organism. The finding correlated with a positive blood culture of Klebsiella pneumoniae and the two-dimensional echocardiography finding of an echogenic atrial thrombus.

Tan et al. (2009) conducted a case report in End-stage renal failure, gram-negative septicaemia, right atrial thrombus (n=1). Multidetector row CT was evaluated on Diagnosis of infected right atrial thrombus. Multidetector row CT incidentally identified a gas-containing filling defect in the right atrium indicative of a thrombus infected by Klebsiella pneumoniae in a patient with end-stage renal failure.
