Multimodal imaging findings of primary inflammatory myofibroblastoma of the gallbladder in adolescents.

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal-derived neoplasm that most commonly arises in the lung. It can also occur in other parts of the body. Primary IMT of the gallbladder is exceptionally uncommon. Due to the absence of large-sample studies, the current understanding of gallbladder IMT remains largely limited to case reports. This article reports the diagnosis and treatment course of a 13-year-old male with inflammatory myofibroblastoma of the gallbladder. It specifically focuses on delineating its distinct imaging characteristics across ultrasonography, computed tomography, and magnetic resonance imaging, aiming to enhance the accuracy of pre-operative diagnosis and provide valuable insights into the literature for this rare condition.
