Cerebellar Neurocysticercosis and Novel Hypotheses.

Cysticercosis, a parasitic infection caused by the larval form of the pork tapeworm, Taenia solium, is increasingly recognized as a cause of epilepsy, headache, and neurological signs when it is located in the brain, optic nerve or spinal cord, known as neurocysticercosis. Anecdotal clinical presentations in patients with severe posterior fossa involvement may include signs of bilateral fourth nerve palsy, facial myokymia, upbeat nystagmus, periodic alternating nystagmus, and rhythmic oculopalatal myoclonus. In patients presenting huge cystic lesions due to posterior fossa neurocysticercosis, intermittent severe headache, epilepsy, signs of raised intracranial pressure, cerebellar signs and cranial nerves signs can be seen as well.We have developed a theoretical explanation for this mechanism based on the hemodynamic characteristic of the blood flow which to be subjected to the opinion of other authors.
