Postchemoembolization liver abscess: findings on hepatobiliary scintigraphy

We describe a 41-year-old man with a 1-week history of nausea and vomiting 1 month after chemoembolization of a liver metastasis. The patient subsequently became febrile and developed right upper quadrant abdominal and midback pain. Findings of initial laboratory and imaging studies (a noncontrast computed tomographic [CT] scan and ultrasound) were not remarkable. Hepatobiliary scintigraphy, performed to rule out cholecystitis, revealed an abnormal area in the right lobe of the liver consistent with a focal bile leak into an abscess cavity. The patient was subsequently treated for liver abscess. In conclusion, hepatobiliary scintigraphy should be considered as a first-line test in the work-up of patients whenever a postchemoembolization complication is considered likely.
