Abstract

CT and MR angiograms (CTA and MRA) often show a double lumen (circulating or non-circulating), double lumen mimics, flaps and flap-like lesions. Interpreting these radiological abnormalities is important since their causes range from benign variants to high-risk disorders. This review illustrates the radiological characteristics of a double lumen or a flap on standard CTA and MRA/MRI and discusses their causes.

CT和MR血管造影显示双腔和皮瓣（及其模拟物）。

CT和MR血管造影（CTA和MRA）常显示双腔（循环或非循环）、双腔模拟、皮瓣和皮瓣样病变。解释这些放射学异常是很重要的，因为它们的原因从良性变异到高风险疾病不等。本文综述了双腔或皮瓣在标准CTA和MRA/MRI上的放射学特征，并讨论了其原因。

期刊介绍： The essential point of Practical Neurology is that it is practical in the sense of being useful for everyone who sees neurological patients and who wants to keep up to date, and safe, in managing them. In other words this is a journal for jobbing neurologists - which most of us are for at least part of our time - who plough through the tension headaches and funny turns week in and week out. Primary research literature potentially relevant to routine clinical practice is far too much for any neurologist to read, let alone understand, critically appraise and assimilate. Therefore, if research is to influence clinical practice appropriately and quickly it has to be digested and provided to neurologists in an informative and convenient way.
