Hepatobiliary scintigraphy in patients receiving hepatic artery infusion chemotherapy.

Hepatic artery infusion chemotherapy is used in the treatment of certain selected hepatic tumors, especially metastatic adenocarcinoma of the colon. Chemical cholecystitis has been recognized recently as a complication of hepatic artery infusion chemotherapy. We performed hepatobiliary scans on ten patients receiving hepatic artery infusion chemotherapy. All ten patients had abnormal hepatobiliary scintigraphy. We present case reports of three patients with abnormal hepatobiliary scans who have required cholecystectomy for symptoms of chemical cholecystitis to illustrate the clinical, scintigraphic, and pathologic findings in these patients.
