From: MRI appearances of hepatic epithelioid hemangioendothelioma: a retrospective study of 57 patients
a, b A 40-year-old male HEH patient with coexistence of target appearance on both T2 weighted and portal phase images. a Target sign on fat-saturated T2-weighted image, consisted of concentric layers including markedly hyperintense in central tumor regions and moderately hyperintense peripheral zone (arrow). b Target sign on portal phase image, consisted of concentric layers including markedly hypointense in central tumor regions and peripheral zones which were moderately hypointense relative to liver parenchyma (arrow). c, d A 51-year-old male rectal carcinoma patients with multiple liver metastasis. c A classic target sign on fat-saturated T2-weighted image (arrow). d Heterogeneous enhancement on portal phase image (arrow), instead of target sign
