Imaging characteristics of intravascular papillary endothelial hyperplasia.

Purpose: Intravascular papillary endothelial hyperplasia (IPEH) is a soft tissue, tumor-like, benign, reactive, vascular proliferation that, although not rare, is uncommonly imaged. We report the imaging findings of intravascular papillary endothelial hyperplasia in 13 patients, highlighting characteristic imaging features.

Materials And Methods: We retrospectively reviewed 13 patients with IPEH who had corresponding MR and/or ultrasound imaging.
