Abstract
Gallbladder wall thickening is a relatively common and nonspecific ultrasonographic finding in the pediatric population, which may pose diagnostic challenges. In the absence of lithiasis, it can be mistaken for acalculous cholecystitis, despite representing distinct entities with different clinical implications and management. While acalculous cholecystitis involves primary inflammation of the gallbladder with a risk of complications, gallbladder edema is usually a reactive phenomenon secondary to systemic processes and follows a self-limited course. In this context, it is essential to avoid overdiagnosis of cholecystitis based solely on imaging findings. Isolated gallbladder wall thickening should always be interpreted in conjunction with clinical presentation, laboratory results, and other imaging findings.
