The urachus is a remnant of the allantois. Failure to obliterate can result in one of four anomalies, urachal cyst being most common. Urachal cysts are relatively rare, especially in adults. This paper presents a patient with an umbilical hernia and a ruptured urachal cyst. A 39-year-old male presented with concern for umbilical hernia, but he also noted drainage. Computed tomography scan showed a urachal cyst and umbilical hernia. The urachal cyst was excised and umbilical hernia closed primarily. The incidence of an urachal cyst is unknown, but persists in roughly 2% of adults. Diagnosis is with ultrasound or CT scan. Management is excision due to risk of urachal carcinoma, which is present in over 50% of specimens. Review of literature did not reveal any other cases of a patient with both an urachal cyst and an umbilical hernia, thus making this case a unique presentation for this condition.
