Urachal Remnants in Patients Presenting to the Emergency Department with Abdominal Pain

Although rare, symptomatic disorders of urachal remnants may present at any age. These disorders should be kept in mind by the emergency physician among the broad list of differential diagnoses accounting for abdominal pain. Urachal cyst and abscess may present with or without drainage from the umbilicus. Drainage from the umbilicus is highly suggestive, but not pathognomonic, of a urachal anomaly, and patients should be imaged to make a definite diagnosis and assist in the management plan.
