Abstract
Gallbladder adenomyomatosis is characterized by invagination of the gallbladder mucosal epithelium into the muscularis propria, which results in the formation of an intramural diverticulum. It primarily affects adults and rarely impacts children and is generally considered a benign disorder. The increased use of high-resolution ultrasonography in children has facilitated the diagnosis of gallbladder lesions in young patients. Various imaging modalities can be utilized to achieve a definitive diagnosis. We report a 17-year-old adolescent girl who presented with nausea and was diagnosed with adenomyomatosis. Although abdominal ultrasonography initially suggested a choledochal cyst, magnetic resonance cholangiopancreatography (MRCP) confirmed that the lesion represented gallbladder adenomyomatosis rather than a choledochal cyst. Following consultation with a pediatric surgeon, a cholecystectomy was planned. This case contributes to the limited pediatric literature on gallbladder adenomyomatosis.
