Eurorad Teaching Case: Intravascular Papillary Endothelial Hyperplasia (Masson’s Tumor)

Intravascular papillary endothelial hyperplasia is a benign reactive vascular lesion that can mimic angiosarcoma on imaging and histology. This Eurorad case illustrates key MRI and ultrasound features to aid differentiation.

• Eurorad educational case, no sample size; illustrates imaging findings.
• Teaches distinction from malignant vascular tumors—a critical radiologic pitfall.
• Case-based review; not a systematic study, limited to single-example teaching.
