Hydatid disease (Echinococcus) of the central nervous system

Area of Science:

• Neurology
• Parasitology
• Infectious Diseases

Background:

• Hydatid disease of the central nervous system (CNS) is a rare parasitic infection, accounting for 2-3% of all hydatid cyst cases globally.
• Spinal hydatid disease is exceptionally rare, predominantly found in sheep and cattle-raising regions like the Mediterranean, including Turkey and Syria.
• Pediatric neurosurgeons in non-endemic areas face diagnostic challenges due to low awareness and nonspecific clinical presentations, posing significant economic burdens in developing countries.

Purpose of the Study:

• To review current literature on brain and spinal hydatid cysts.
• To understand the epidemiology, diagnostic accuracy, and therapeutic advancements for CNS hydatid disease.
• To highlight the importance of clinical suspicion, MR imaging, and surgical strategies for effective management.

Main Methods:

• Comprehensive literature review of hydatid cyst of the brain and spine.
• Analysis of epidemiological data, diagnostic modalities, and treatment outcomes.
• Discussion of current and emerging surgical techniques and prevention strategies.

Main Results:

• Hydatid disease of the CNS is uncommon, with spinal involvement being particularly rare.
• Magnetic Resonance (MR) imaging has significantly improved diagnostic accuracy for CNS hydatid cysts.
• Complete, intact surgical removal of the cyst is the primary goal for successful treatment and cure.

Conclusions:

• A high index of clinical suspicion is crucial for diagnosing CNS hydatid disease, especially in endemic regions.
• MR imaging plays a vital role in accurate diagnosis and surgical planning.
• Improving surgical strategies and implementing nationwide prevention programs are essential for controlling hydatid disease.
