Computed tomography (CT) and ultrasonography (US) are ideally suited for demonstrating urachal remnant diseases. A patent urachus is demonstrated at longitudinal US and occasionally at CT as a tubular connection between the anterosuperior aspect of the bladder and the umbilicus. An umbilical-urachal sinus manifests at US as a thickened tubular structure along the midline below the umbilicus. A ...

Primary umbilical endometriosis is a rare disorder and is defined as the presence of ectopic endometrial tissue within the umbilicus. A patient with painful mass in the umbilicus during menstrual period is studied in this paper. The possibility of subcutaneous endometriosis should be considered when an umbilical mass is detected despite the absence of previous surgery. In this case, urachal can...

A female baby of one-and-a-half-year old presented with extrusion of ventriculoperitoneal (VP) shunt through umbilicus. On exploration, the urachal remnant was found perforated by VP shunt and the tube exteriorized through umbilicus. Child was managed successfully with excision of urachal remnant, removal of VP shunt, antibiotic treatment and re-insertion of shunt.

PURPOSE We examined the presentation, diagnosis and management of radiologically detected pediatric urachal anomalies and assessed the risk of malignant degeneration. MATERIALS AND METHODS Our radiology database (2000 to 2012) was queried for all children younger than 18 years who were diagnosed with a urachal anomaly radiographically, and the operative database was used to determine those wh...

As urachal adenocarcinomas are rare cancers, experience with diagnosing and staging them are limited. To help illustrate CT and PET imaging findings and the role they each play in the workup of urachal adenocarcinomas, we present the case of a 43 y.o. male who was diagnosed at our institution with a T3aN0M0 high grade mucin-producing urachal adenocarcinoma. Merissa Zeman, Ethan Silver and Esma ...

This report describes a case of mucinous adenocarcinoma with superficial stromal invasion and villous adenoma originating in the dome of the urinary bladder. Although no urachal remnants were identified, the location suggested urachal derivation. Only two previous cases of urachal adenocarcinoma with features of early stromal invasion associated with a villous tumour have been described.

BACKGROUND Abdominal tuberculosis (TB) is an uncommon affliction in adolescence. It is usually associated with pulmonary tuberculosis. The disease is caused by lymphohaematogenous spread after primary infection in the lung or ingestion of infected sputum and has a typically protean and nonspecific presentation. The occurrence of TB in an urachal remnant is probably from the contiguous spread of...
