Emphysematous cholecystitis as a complication of hepatic arterial embolization.

We describe a case of emphysematous cholecystitis that developed 2 weeks after hepatic arterial embolization. Angiographers should be alert to the possibility of this complication developing under conditions when the cystic artery is not visualized on the post embolization arteriogram while present on the diagnostic study before embolization.
