Inguinal or inguinoscrotal herniation of the bladder is not uncommon and has been estimated to comprise 1% to 3% of all inguinal hernias. The appearance of hernias on ultrasonography, intravenous pyelography, cystography, and computed tomography has been described previously but no instance of correlation with magnetic resonance (MR) imaging has been documented. Nevertheless, herniated bladders can be encountered fortuitously during abdominal MR imaging, and the radiologist should be familiar with their appearance. We present a case of unsuspected paraperitoneal indirect inguinal bladder herniation demonstrated by MR. Appearance on MR is characteristic, and this modality may be useful for differentiating the several types of inguinal hernias of the bladder because of its superior soft tissue contrast. In addition, MR imaging can be used to perform imaging in any plane and dynamic examinations during straining.

Urinary Bladder01:23

Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
