Angiographic findings in multiple bile-duct hamartomas of the liver.

The angiographic appearance in a patient with multiple bile-duct hamartomas of the liver is described. The lesions showed abnormal vascularity, consisting of grapelike clusters of small rings, which could be confused with other benign and malignant conditions demonstrable by angiography; however, it may ultimately prove to be characteristic of this uncommon lesion. The angiographic differential diagnosis is discussed.
