Combined resection of the right liver lobe and retrohepatic inferior vena cava to treat hepatic alveolar echinococcosis: A case report.
2017
RATIONALE: Hepatic alveolar echinococcosis (HAE) is a potentially fatal and chronically progressive infestation that is caused by the multivesicular metacestode of Echinococcus multilocularis (EM). HAE behaves like a malignant tumor and has been referred to as "worm cancer." The main treatment method for HAE is surgical resection. PATIENT CONCERNS: We present a 41-year-old Tibetan alveolar echinococcosis (AE) patient with AE lesions invading the right liver lobe and retrohepatic inferior vena cava (RHIVC). DIAGNOSES: The patient was diagnosed with HAE based on results obtained from ultrasound examination, computed tomography, liver 3-dimensional reconstruction, serology tests, clinical presentation, and surgical exploration. The final pathology report confirmed the diagnosis as HAE. INTERVENTIONS: A radical surgery that combined resection of the liver and RHIVC was performed successfully. OUTCOMES: The patient had an uneventful postoperative recovery and a good prognosis. LESSONS: When lesions of the liver significantly violate the RHIVC, resecting the RHIVC without reconstruction may be considered if possible.
