Hepatic Hemangioendothelioma

Michael P. D'Alessandro, M.D.
Peer Review Status: Internally Peer Reviewed


Clinical Presentation:
Hemangioendotheliomas usually present in the first 6 months of life as abdominal masses complicated by congestive heart failure due to the high cardiac output associated with arteriovenous shunting from the lesion. Fifty percent of these lesions have associated cutaneous hemangiomas. They are the most common benign liver tumors in childhood.

Etiology/Pathophysiology:
Vascular malformation that usually involutes spontaneously or with the use of steroids.

Pathology:
Not applicable

Imaging Findings:
Usually involves the entire liver. The diagnosis may be made by nuclear medicine liver scan as the hemangioendothelioma has rapid appearance of tracer in it with delayed clearance of tracer with inhomogeneous distribution of the tracer and there is often early cardiac recirculation due to arteriovenous shunting.
