Abstract

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.
