Lateral projection of right ICA angiogram (A–C) and axial T1-weighted gadolinium-enhanced MR imaging (D) demonstrate the typical imaging features of a capillary vascular malformation in a 17-year-old male patient with HHT. A focal subcentimeter blush (arrows) is identified on the arterial phase of a right carotid angiogram, in the frontal, temporal, and parietal regions, in keeping with multiple capillary telangiectasia. Magnified view of the right parietal lesion shows typical angiographic features, with vascular blush identified in the arterial (B) persisting into early venous phase (C); no arteriovenous shunting, dilated arterial feeder, or dilated draining vein are seen. MR imaging appearance of the right parietal lesion demonstrates the typical features of fluffy contrast enhancement in a superficial cortical/subcortical location, without abnormal vascular dilation (D, arrow).
