Urachal remnants in asymptomatic children: sonographic morphology.

1991

The sonographic morphology of urachal remnants is not well known and findings tend to be misinterpreted. We present urachal remnants in 16 asymptomatic children (1 week-16 years). In the prevesical part two different types of urachal remnants were found: the tubular type with a small outer muscle wall and the fusiform type with a muscle wall thickness up to 12 mm. Further subvariants are presented. Differential diagnosis of the fusiform type includes urachal cyst and tumorous muscle thickening.

Urachal Signet-ring Cell Carcinoma, A Rare Variant of Vesical Adenocarcinoma: Incidence And Pathologicalcriteria

1978

Abstract Of 715 cases of vesical tumors reviewed 18 adenocarcinomas were selected for further study, 5 of which fulfilled all criteria of urachal origin. Herein is reported 1 rare case of such a carcinoma of the signet-ring cell type and the morphological criteria of this variant are discussed briefly. After undergoing radical cystectomy and ureterosigmoidostomy the patient has been free of recurrent tumor or metastasis for 6 years.

Sonographie von Urachusanomalien im Kindesalter

1991

The sonographic appearances of urachal anomalies are illustrated by six patients with persistent urachus (n = 1), infected persistent urachus (n = 1), urachal sinus (n = 1), infected urachal cyst (n = 2) and urachal diverticulum (n = 1). The anomalies were diagnosed sonographically in every case. Symptomatic patients were treated surgically.
