Abstract:
Gallbladder diverticulum is a rare developmental anomaly characterized by a herniation-like outpouching of the gallbladder wall. The reported incidence in autopsy studies ranges from 0.0008% to 9%. Most reported cases have been diagnosed postoperatively, and the role of ultrasonography in their detection remains uncertain. Based on our experience, we present a set of ultrasound features that may aid in the identification of gallbladder diverticula. Although often incidental, some diverticula may mimic cholecystitis or pose challenges during cholecystectomy. Despite limited literature representation, ultrasonography appears to be a reliable modality for their preoperative assessment. Greater awareness of this entity among sonographers may improve its recognition and reporting quality, enhancing diagnostic accuracy.
