Urinary bladder diverticulum as an unusual content of the inguinal canal

The inguinal urinary bladder hernia is a rare pathology observed mostly in males. A new case of asymptomatic reducible acquired inguinal hernia was revealed in a 54-year-old male during computed tomography (CT) undertaken for oncological follow-up. The right nephrectomy was previously performed due to clear cell carcinoma. The hernia was not visible on the CT 6 months before and on ultrasound performed after voiding. Slight herniation with a wide invagination of transversalis fascia but with empty bladder was seen on CT 4 months after the initial detection of hernia
