C) D) Images in a 66-year-old woman with a right upper quadrant abscess that occurred after cholecystectomy. (a) Transverse contrast-enhanced supine CT image shows abscess (arrow) in the gallbladder fossa. (b) Sagittal US image of the abscess obtained immediately prior to US-guided drainage shows multiple septations (arrow). (c) Transverse contrast-enhanced supine CT image shows residual abscess collection (arrow) identified next to the drainage catheter. (d) Transverse contrast-enhanced supine CT image obtained following intracavitary administration of 4 mg of tPA in 50 mL of 0.9% saline twice daily for 3 days shows no residual collection. The catheter was then removed, and there was no recurrence of the abscess cavity.
