(A) Greyscale imaging of the left lobe of the liver with an ill-defined lesion (large arrow), containing locules of gas. (B) Following administration of intravenous ultrasound contrast the non-enhancing liver abscess with multiple locules is clearly seen. (C and D) Dilute ultrasound contrast injected via an in-dwelling catheter within one locule, confirms correct placement and confirms connections between multiple locules (thin and thick arrows)
