Case Report: Simultaneous hepatic and renal echinococcosis in a child: a multidisciplinary approach.

Introduction: Echinococcosis caused by Methods: A 5-year-old boy from a pastoral region in Tibet, China, was admitted due to a palpable abdominal mass detected one month prior. Imaging studies, including CT, identified multiple echinococcal lesions in the liver and a large cystic mass in the kidney. Serological assays confirmed Results: The patient underwent radical multiple pericystectomies of the liver and endocystectomy of the right renal echinococcal cyst. Intraoperatively, multiple firm, translucent masses in the liver and a large cystic mass in the right kidney were found, both confirmed to be infected with Discussion: This case underscores the complexity and rarity of simultaneous hepatic and renal echinococcosis in children. Early diagnosis through detailed medical history, imaging studies, and serological assays is crucial. The multidisciplinary approach, including tailored surgical strategies and postoperative management, was essential for a favorable outcome. The success of pericystectomy highlights the importance of organ-sparing techniques in pediatric patients. However, potential complications like transient hypernatremia emphasize the need for vigilant postoperative monitoring and supportive care. Future research should focus on improving diagnostic precision, surgical methodologies, and postoperative care in children.
