In multicystic renal diseases, cyst infection is a complex issue because of the absence of validated diagnostic methods. Unilateral renal cystic disease is a rare multicystic disease, believed to have an acquired maldevelopmental origin. Unilateral renal cystic disease is often confused with autosomal dominant polycystic kidney disease but has some distinguishing characteristics: unilateral localization, negative family history, and no progression to chronic renal failure. We describe a case of unilateral renal cystic disease with cyst infection that could be detected by diffusion-weighted magnetic resonance imaging, but not by conventional imaging techniques. Diffusion-weighted magnetic resonance imaging can be useful for detecting infected cysts, especially in multicystic renal diseases.
在多囊肾病中，由于缺乏经过验证的诊断方法，囊感染是一个复杂的问题。单侧肾囊性疾病是一种罕见的多囊疾病，据信具有获得性发育不良的起源。单侧肾囊性疾病常与常染色体显性多囊肾病相混淆，但具有一些区别特征：单侧定位、阴性家族史和无进展为慢性肾衰竭。我们描述了一例单侧肾囊性疾病伴囊感染的病例，该病例可通过弥散加权磁共振成像检测，但不能通过常规成像技术检测。弥散加权磁共振成像可用于检测感染性囊肿，特别是在多囊肾病中。
