The urachus revisited: Multimodal imaging of benign & malignant urachal pathology.

The urachus revisited: Multimodal imaging of benign & malignant urachal pathology. Br J Radiol. 2020 Feb 11;:20190118 Authors: Das JP, Vargas HA, Lee A, Hutchinson B, O'Connor E, Kok HK, Torreggiani W, Murphy J, Roche C, Bruzzi J, McCarthy P Abstract The urachus is a fibrous tube extending from the umbilicus to the antero superior bladder dome that usually obliterates at week 12 of gestation, becoming the median umbilical ligament. Urachal pathology occurs when there is incomplete obliteration of this channel during foetal development, resulting in the formation of a urachal cyst, patent urachus, urachal sinus or urachal diverticulum. Patients with persistent urachal remnants may be asymptomatic or present with lower abdominal or urinary tract symptoms and can develop complications. The purpose of this review is to describe imaging features of urachal remnant pathology and potential benign and malignant complications on ultrasound, computed tomography (CT), positron emission tomography (PET) CT and magnetic resonance imaging (MRI).
