[Échinococcose alvéolaire].

Area of Science:

• Parasitology
• Hepatology
• Infectious Diseases

Background:

• Alveolar echinococcosis is a severe parasitic zoonosis mimicking liver cancer.
• It obstructs bile ducts and vessels, potentially metastasizing to distant organs.
• Historically, it had a poor prognosis, but recent advances have transformed outcomes.

Purpose of the Study:

• To highlight the evolving epidemiology of alveolar echinococcosis.
• To discuss the challenges in diagnosis and management due to changing patterns.
• To emphasize its emerging role as an opportunistic infection.

Main Methods:

• Review of recent epidemiological data and clinical case reports.
• Analysis of diagnostic imaging and treatment advancements.
• Assessment of the impact of immunosuppressive therapies.

Main Results:

• The endemic area for alveolar echinococcosis in Europe has significantly expanded.
• Case numbers have more than doubled in established endemic regions.
• The disease is increasingly diagnosed incidentally and in non-traditional populations, including immunocompromised patients.

Conclusions:

• Prognosis has improved due to earlier diagnosis and better treatments.
• Alveolar echinococcosis is now frequently an 'opportunistic infection'.
• The expanding range and atypical presentations complicate differential diagnosis and patient care.
