Abstract

Echinococcosis is a human parasitic disease widespread in many countries because of population migration, occupational risk factors, and increased tourism. The clinical symptoms are non-specific and manifest late. Echinococcosis is often discovered incidentally in clinical practice. Diagnostic errors can result from low awareness of healthcare professionals regarding echinococcosis in regions with low incidence rates.

This article describes a case report of imported echinococcosis in a patient with chickenpox (varicella) diagnosed at Infectious Diseases Clinical Hospital No. 2 of the Moscow Healthcare Department in April 2021. The patient came from Kyrgyzstan, where he worked as a sheep farmer. Inpatient ultrasound and computed tomography of the abdomen and retroperitoneum revealed multiple cystic liver lesions of parasitic origin. An enzyme-linked immunosorbent assay revealed the IgG antibodies to Echinococcus antigens.

This clinical case highlights the ongoing relevance of echinococcosis in Russia and underscores the need for a comprehensive analysis of clinical, epidemiological, laboratory, and imaging data. These findings also suggest the importance of raising awareness among healthcare professionals about this infection, especially when treating migrants from endemic regions with cystic liver lesions and patients in high-risk groups.
