Abstract

The urachus is an embryonic remnant that usually involutes before birth. Abnormal persistence of this structure can lead to infectious or neoplastic complications later in life. We report a case of an 84-year-old man that presented with a urachal complex mass which, after proper investigation, revealed to be a urachal abscess. Urachal abscesses are rare and usually occur in severe infections. Urachal abscesses can be indistinguishable from urachus carcinoma on imaging studies. This article reviews the clinical and imaging aspects of urachal abscess and carcinoma and possible differentiating elements in imaging. However, definitive diagnosis usually depends on a biopsy or fluid aspiration.

摘要

脐尿管是一种胚胎残余物，通常在出生前退化。该结构异常持续存在可导致日后生活中出现感染或肿瘤并发症。我们报告一例84岁男性病例，其表现为脐尿管复合体肿物，经适当检查后发现是脐尿管脓肿。脐尿管脓肿罕见，通常发生于严重感染时。在影像学检查中，脐尿管脓肿可能与脐尿管癌难以区分。本文综述了脐尿管脓肿和癌的临床及影像学表现以及影像学上可能的鉴别要点。然而，明确诊断通常依赖于活检或液体抽吸。
