Highlights

  • Alveolar Echinococcosis is a rare but potentially fatal parasitic infection primarily affecting liver.

  • The diagnosis and treatment can be difficult and clinical misinterpretation as malignancy is not rare.

  • The principal treatment of Alveolar Echinococcosis is surgery accompanied with chemotherapy.

Abstract

Introduction

Human Alveolar Echinococcosis – Alveolar Hydatid disease (AE) is an omitted zoonotic infection presenting with focal liver lesions. Cause of AE is a larval stage of Echinococcus multilocularis tapeworms.

Case presentation

In this report an extraordinary case of a 38 year-old female examined due to 2 liver tumors and 2 pulmonary nodules is described. The patient underwent pulmonary and liver surgery for suspected advanced cholangiocellular carcinoma and surprisingly AE was found.

Discussion

Distinguishing intrahepatic AE from other focal liver lesion can be complicated and in many cases is diagnosed incorrectly as intrahepatic cholangiocarcinoma or other liver malignancy.

Conclusion

AE is a rare but potentially fatal parasitic infection primarily affecting liver, although it can metastasise to lung, brain and other organs. The diagnosis and treatment can be difficult and clinical misinterpretation as malignancy is not rare. The principal treatment of AE is surgery accompanied with chemotherapy.
