Key Points

The aim was to diagnose and treat an unusual giant neurocysticercosis in a 45-year-old man.
Clinical evaluation of symptoms including neck pain and blurred vision.
Magnetic resonance imaging to identify the cyst location and size.
Surgical removal of the cyst through suboccipital craniectomy.
Western blotting to confirm the diagnosis with anti-cysticercus antibodies.
Magnetic resonance imaging revealed a large 6×4.8 cm cyst in the posterior fossa.
Surgical intervention successfully removed the cyst and alleviated symptoms.
Western blotting confirmed the diagnosis as neurocysticercosis.

Abstract

A 45-year-old man visited with suboccipital and posterior neck pain accompanied with blurred vision, dysarthria and paralytic feeling for 7 months. Magnetic resonance imaging revealed large eccentrically located cyst (6×4.8 cm) within posterior fossa which compressed right side cerebellar hemisphere and brainstem. The transparent cyst wall and fluid were removed by suboccipital craniectomy and the symptoms disappeared. Western blotting of the patient's cyst fluid reacted positively with the anti-cysticercus 150 kDa antibody and therefore the giant cyst was proved to be unusual giant neurocysticercus.
