A 37-year-old male presented to the emergency department with the complaint of periumbilical abdominal pain, radiating to just above pubic symphysis. The patient reported that the pain was worse with urination and associated with chills and nausea. This case reports discusses the Emergency Department (ED) course and subsequent treatment of a patient found to have an infected urachal cyst, a previously asymptomatic embryological anomaly in an otherwise healthy middle-aged adult male. This is a crucial diagnosis to make in order to avoid the potential for significant morbidity and/or mortality, given the unlikely symptomatic source.
