A 10-year-old male patient presented with anterior midline pre-sternal chest wall mass. MRI chest wall shows a well-defined oval shaped soft tissue mass with related dilated vascular channels and no intra-thoracic extension, eliciting hypointense signal intensity in T1WI (a) and high signal intensity in T2 WI (b) with facilitated diffusion pattern in diffusion WI (c) and ADC map (d). The ADC value was 2.08 ± 0.05 × 10−3 mm2/s, and the mass was pathologically proven to be hemangioma
