Misdiagnosis of a Patient with Hepatic Alveolar Echinococcosis with Hepatapostema: A Case Report.

Alveolar echinococcosis (AE) is an important zoonotic tropical disease in China that affects people living in western endemic areas. The disease is prone to occur in the liver with a characteristic similar to slow-growing malignant tumors. We report a 31-year-old male patient with serious complication after hepatorrhaphy, who had presented with clinical manifestations of hepatapostema with infection. Ultrasound (US) and computer tomography (CT) are two important medical imaging modalities to diagnose hepatic AE. Based on the medical history, clinical findings, laboratorial and imaging results, the patient was misdiagnosed with hepatapostema. A series of subsequent treatments were ineffective. Finally, partial hepatectomy was performed, and postoperative pathological results confirmed hepatic AE. The patient has now recovered.
