Liver schwannoma: findings on MRI

Magnetic resonance imaging features of benign liver schwannoma in a 52-year-old woman are described. An oval shaped, 4.4x3.6x2.9-cm lesion was located in Segment 7 of the right hepatic lobe. The lesion was hypointense on T(1)-weighted images and mixed hypo- and hyperintense on T(2)-weighted images. On serial contrast-enhanced images, the lesion revealed gradually increasing centrilobular enhancement. The tumor was surgically removed thereafter.
