Bladder Rupture: Distinguishing Intraperitoneal and Extraperitoneal Patterns on Imaging

Bladder rupture is classified as intraperitoneal (contrast outlines bowel loops, ascites) or extraperitoneal (flame-shaped pelvic extravasation). Intraperitoneal rupture requires surgical repair; extraperitoneal rupture is typically managed conservatively with catheter drainage.

• Educational review covering the imaging appearance, classification, and management implications of bladder rupture on CT cystography.
• Key imaging distinction: intraperitoneal rupture shows contrast within the peritoneal cavity outlining bowel; extraperitoneal rupture shows contrast confined to the perivesical space with a flame-shaped pattern.
• Based on a single educational blog post; no new primary research data or patient cohort reported.
