The diagnosis of traumatic renal artery occlusion by CT is based on finding the cortical rim sign, nonopacification of the pelvocalyceal system, and occasionally direct visualization of the thrombosed renal artery. We present four patients with renal artery occlusion who have an unusual pattern of medullary enhancement that has a vermiform and spoke-wheel appearance. It is important to realize that this enhancement does not represent functional renal tissue with a partially occluded renal artery. Instead, it is part of the spectrum of findings seen with complete occlusion of the renal artery.
CT诊断创伤性肾动脉闭塞是基于发现皮质边缘征、肾盂肾盏系统不显影，偶尔可直接观察到血栓形成的肾动脉。我们报告了4例肾动脉闭塞患者，其髓质强化呈现出一种蠕虫状和辐轮状的异常模式。重要的是要认识到这种强化并不代表肾动脉部分闭塞时的功能性肾组织。相反，它是肾动脉完全闭塞所见一系列表现的一部分。
