When the urachal tract is not completely obliterated during embryonic development, bladder diverticulum, urachal cyst, umbilical polyp, or patent urachus may result. Therefore, making a differential diagnosis prior to surgery is not easy. A 30-year-old woman presented to the outpatient clinic with severe abdominal pain in the suprapubic and infraumbilical regions of 12 hours of evolution. There were no urinary symptoms, and she was afebrile. Physical examination revealed periumbilical tenderness and intense pain on abdominal palpation in the suprapubic and abdominal regions. An ultrasound scan revealed a patent urachus. The striated structure was present between the bladder and the umbilicus. After undergoing preoperative examinations, the patient was submitted to surgical treatment, and the final pathology of the resected segment confirmed the ultrasound diagnosis. Urachal pathology in adulthood is rare. Often its presentation as acute abdominal pain is nonspecific and, as such, may cause many diagnostic problems. Differential di...
