Appendicovesical fistula is a rare complication associated with appendicitis, Crohn's disease, or appendiceal tumors, posing significant diagnostic challenges. We reported a pediatric case of appendicovesical fistula that remained undiagnosed by non-contrast computed tomography, fluoroscopic voiding cystourethrography (VCUG). Although identified during cystoscopy, its connection to the fistula site could not be determined. However, the transvesical contrast-enhanced ultrasound clearly demonstrated the presence of fistula. Subsequently, laparoscopic appendectomy and bladder repair were performed successfully, leading to complete recovery in the patient. To our knowledge, this is the first reported diagnosis of appendicovesical fistula in children using contrast-enhanced ultrasound.
膀胱阑尾瘘是一种罕见的并发症，与阑尾炎、克罗恩病或阑尾肿瘤有关，给诊断带来了重大挑战。我们报告了一例儿科膀胱阑尾瘘病例，其在非对比计算机断层扫描、荧光透视排尿性膀胱尿道造影（VCUG）中未被诊断。尽管在膀胱镜检查中发现了瘘管，但无法确定其与瘘管部位的连接。然而，经阴道对比增强超声明确显示了瘘管的存在。随后，成功进行了腹腔镜阑尾切除术和膀胱修补术，患者完全康复。据我们所知，这是首例使用对比增强超声诊断儿童膀胱阑尾瘘的病例报告。
