“Look Before You Leap”: Urachal Mass in Adults

Diseases of the urachal remnant can present at any age. Urachal adenocarcinoma is the most frequent cause of urachal mass in adults, albeit infected urachal cyst constitutes a significant number. Lack of typical clinical and imaging findings combined with absence of definitive guidelines makes evaluation of urachal mass in adults very challenging. We present a case of a 58-year-old man presenting with an urachal mass with overlapping clinical and imaging findings mimicking urachal malignancy which later turned out to be an infected urachal cyst.
