[Magnetic resonance imaging findings of intravascular papillary endothelial hyperplasia].

This paper analyzed the imaging data of intravascular papillary endothelial hyperplasia (IPEH) in 5 cases, with 1 male, 4 females, aged 28-61 years. MRI of IPEH revealed well-demarcated masses with central iso-or hypointensity and peripheral hyperintensity on T2-weighted image(T2WI), as well as peripheral enhancement or hyperintensity on T2WI with/without hypointense foci, as well as homogeneous enhancement or heterogeneous enhancement with nonenhanced foci. CT demonstrated iso-or slightly hyperdense, well-circumscribed mass with bone destruction or calcification.
