Kasabach-Merritt syndrome complicating a giant hemangioma of the liver: A case report

N Amsiguine et al. Radiol Case Rep. .

Abstract

Liver hemangiomas are the most common benign tumors of the liver with a prevalence of 1%-20% according to autopsy series. They can in some cases reach measurable sized. These giant hemangiomas can have fatal complications such as hemorrhaging, intraperitoneal rupture, mass of effect and Kasabach-Merritt syndrome. We report an adult case in which recent right quadrant pain revealed a liver hemangioma associated with Kasabach-Merritt syndrome.

Keywords: Abdominal pain; Computed tomography; Giant hepatic hemangioma; Kasabach-Merritt syndrome; Magnetic resonance imaging.
