Figure 15c. Capillary hemangioma of the thigh. (a) Coronal maximum-intensity-projection MR angiogram shows a contrast-enhanced microlobular lesion in the left thigh (arrow). (b) Graph of a time-signal intensity curve demonstrates a fast perfusion-enhancement pattern. (c) Low-power photomicrograph (original magnification, x40; H-E stain) shows capillaries of varying sizes (arrows).
