A 70-year-old male patient with recurrent abdominal pain, ultrasound of the abdomen demonstrates a high echogenicity lesion of the right liver lobe. Quad-phase study of the liver was done to assess the nature of the lesion. The hepatic lesion followed the criteria of benign hepatic hemangioma with continuous fill in of contrast on all phase. Note that the lesion became "smaller" on the delayed phase if compared to the pre-contrast phase.
Cavernous hemangiomas are composed of multiple, large vascular channels supported by collagenous walls. They are frequently asymptomatic and may be discovered at imaging. Typical hemangiomas measure less than 5 cm; when larger they are called giant hemangiomas.
