Bottom Line: Central vessels are characteristic imaging finding of Epi-HAML, which usually were displayed by dynamic contrast imaging.In this paper, we displayed the central vessels of Epi-HAML invisible on conventional MR images using a new developed abdominal susceptibility-weighted imaging (SWI).To the best of our knowledge, this is the first description for the role of SWI in characterization of Epi-HAML.

ABSTRACT
Epithelioid hepatic angiomyolipoma (Epi-HAML) is a rare benign mesenchymal tumor with malignant potential. Most of Epi-HAML contains no or only a minimal amount of adipose tissue and poses a diagnostic challenge. Central vessels are characteristic imaging finding of Epi-HAML, which usually were displayed by dynamic contrast imaging. In this paper, we displayed the central vessels of Epi-HAML invisible on conventional MR images using a new developed abdominal susceptibility-weighted imaging (SWI). To the best of our knowledge, this is the first description for the role of SWI in characterization of Epi-HAML.

The mass shows inhomogeneous hypointensity on T1WI (a) and hyperintensity on T2WI ((b) arrowhead) with inhomogeneously intense enhancement at arterial phase (c) and persistent enhancement at portal venous phase (d). SWI images (e) reveal numerous branching punctate or curved central microvessels (arrow). The continuity of the central microvessels could be better visualized on MinIP images of SWI ((f) arrow).

Mentions: At MR images, the mass showed heterogeneous hyperintensity on T1WI (Figure 2(a)) and clearly hyperintensity on T2WI (Figure 2(b)). No fat components were detected at MR images. Dynamic imaging showed a heterogeneous hypervascular mass after gadolinium administration (Figures 2(c) and 2(d)). SWI could visualize central microvasculature with better conspicuity (Figure 2(e)), which appeared as branching curvilinear configuration with hypointensity on minIP images of SWI (Figure 2(f)).
