Abstract

Hepatic sinusoidal dilatation (HSD) is a rare vascular disorder characterized by focal dilatation of the sinusoidal spaces in the liver. In most cases, it may be associated with venous outflow impairment. In addition, this histological change could occur in a number of systemic and hepatic conditions in the absence of hepatic venous obstruction. However, the pathogenesis has not yet been elucidated. To the best of our knowledge, imaging findings in a case of localized HSD without any additional medical disorder or oral contraceptive therapy have not been described previously in the literature written in English. Here, we describe imaging findings in a case of localized HSD mimicking a hepatic tumor, focusing on the useful findings on the gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced hepatobiliary phase MR image.
