Background Lentiform fork sign is a neuroradiological abnormality which is encountered in the clinical practice associated with uremic encephalopathy, dialysis disequilibrium syndrome and metabolic acidosis. Case presentation We describe here a case of this neuro-radiological abnormality which was encountered in a patient with uraemia and high anion gap metabolic acidosis who presented with generalised convulsion and later had some tremor in her hands. In our patient, there were few predisposing factors which might have possibly resulted in this abnormality chronic kidney disease, diabetes mellitus, and metabolic acidosis. Conclusion The Lentiform fork sign is a rare occurrence which can be related to a long list of toxic and metabolic causes but in conjunction with metabolic acidosis in chronic kidney disease patients, it can narrow down this list of alternate diagnosis.

一例伴有癫痫发作的高阴离子间隙代谢性酸中毒尿毒症患者的豆状叉征：来自爱尔兰西北部的病例报告

背景 豆状叉征是一种神经放射学异常，在临床实践中遇到与尿毒症脑病、透析不平衡综合征和代谢性酸中毒有关。病例介绍 我们在此描述一例这种神经放射学异常的病例，该病例发生在一名患有尿毒症和高阴离子间隙代谢性酸中毒的患者身上，该患者表现为全身抽搐，后来双手有些震颤。在我们的患者中，几乎没有可能导致这种异常慢性肾病、糖尿病和代谢性酸中毒的诱发因素。结论 Lentiform fork 征是一种罕见的现象，可能与一系列毒性和代谢原因有关，但与慢性肾脏病患者的代谢性酸中毒有关，
