Summary
Diverticulitis can cause colovesical fistulas, mimicking bladder cancer. Pathologic examination is crucial for diagnosing bladder masses, as seen in a case of recurrent urinary infections.
Area of Science:
- Urology
- Gastroenterology
- Pathology
Background:
- Urothelial cell carcinomas are the most common urinary bladder tumors.
- Inflammatory and non-neoplastic conditions can present as bladder malignancies.
- Diverticulitis can lead to colovesical fistula and bladder wall abscess, mimicking a tumor.
Observation:
- A 60-year-old woman presented with recurrent urinary infections.
- A focal bladder mass was detected during examination.
- The mass was found to be a colovesical fistula.
Findings:
- The bladder mass was pathologically confirmed as a colovesical fistula.
- The fistula was a complication of sigmoid diverticulitis.
- This highlights a rare presentation of diverticulitis.
Implications:
- Accurate diagnosis of bladder masses is essential.
- Colovesical fistulas should be considered in the differential diagnosis of bladder masses.
- Pathologic examination is critical for differentiating malignancy from inflammatory conditions.

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...

145
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
