Urachal Lesions: Unveiling the Role of Imaging in Accurate Diagnosis

Urachus is an embryonic remnant structure formed due to the involution of the cloaca and allantois that serves as a communication channel between the developing urinary bladder and the umbilicus via the allantois. Normally, this structure obliterates by mid-gestation and transforms into a fibrous cord known as the median umbilical ligament.[1] However, incomplete involution leads to various congenital urachal anomalies, which can be detected incidentally on imaging or the patient can present with urinary symptoms or nonspecific abdominal symptoms both in the pediatric and adult population predisposing the patient to infections, inflammation, and malignancy, therefore increasing the morbidity.[2]
