Hemangiomas are the most common benign vascular neoplasms of infancy. Congenital hemangiomas proliferate in utero, and are fully formed at birth. They are usually solitary. Generalized forms are exceptional. The liver is the second most common site of hemangiomas after the skin. When >5 cutaneous hemangiomas are present, screening abdominal ultrasound is recommended. Based on the degree of liver parenchyma involvement, 3 hepatic hemangiomas' subtypes are defined: focal, multifocal, and diffuse. Hepatic hemangiomas' clinical presentation varies from asymptomatic to life-threatening. High output cardiac failure, consumptive coagulopathy, abdominal compartment syndrome, and liver dysfunction are possible complications. We report an unusual case of symptomatic congenital hemangiomatosis in a male infant born with innumerable generalized cutaneous hemangiomas whose screening abdominal ultrasound revealed multifocal hepatic hemangiomas with extensive mixed shunts. We aim to highlight this unique entity with severe associated complications and stress the role of imaging at initial presentation, for follow-up, and to guide therapeutic choices.
