Abstract

We describe the imaging findings in a rare case of multifocal nodular form of hepatic epithelioid hemangioendothelioma on ultrasound (US) and dynamic contrast‐enhanced spiral computed tomography (CT) and MRI. The nodules showed multilayered target appearance on MR images with prominent peripheral rim with high signal intensity (SI) on T1‐weighted and very low SI on T2‐weighted images, corresponding to thrombosed vascular channels. The above combination of imaging findings is to our knowledge distinct and should suggest the diagnosis of hepatic epithelioid hemangioendothelioma. J. Magn. Reson.
