摘要: The author studied a superficial temporal vein running anteroposteriorly within the occipitotemporal sulcus, “occipitotemporal vein”, which, when prominent, could be thought to simulate “venous angioma” on MRI. A cadaver (n=50), MRI (n=200), and CT (n=50) study was undertaken examine incidence, detectibility, size, location, drainage of vein. It an approximately 3 mm wide, 2–5 cm long structure. present in 83% cadavers (52% bilaterally), clearly identifiable 73% (43% 8% studies. In 18% totally absent, it not seen 27% examinations. can distinguished from venous angioma by its particular location course, lack intraluminal bright signal spin-echo T2-weighted and/or contrast-enhanced T1-weighted images. addition, angiomas are usually intraparenchymal, whereas is vessel.
