Cysticercosis lesions in basal ganglia are common but clinically silent

A large silent cysticercus occupying most of the medulla oblongata

“…Our patient, however, had minimal symptomatology and attended the hospital because of a seizure caused by one of his parenchymal brain cysts, not related to the brainstem cyst. Similar lack of clinical manifestations has been reported in other locations such as basal ganglia involvement [5]. Tractography nicely demonstrated that the slow growth of the parasitic cyst displaces the nerve tracts preserving their integrity and functionality.…”

Comment on: Neurocysticercosis presenting as Parkinsonism

“…[1,3] Moreover, we are not sure whether the previously reported case had anatomically symmetrical NCC. However, the concomitant presence of NCC in basal ganglia associated with Parkinsonism has been reported previously once as a single case report and not series of cases.…”

“…[1] Indeed, neurocysticercosis at basal ganglion is not rare. [3] Therefore, it is questionable whether the present cases are only accidental concomitant fi ndings or not. At least, another case was previously reported by Cavalcanti.…”

Neurocysticercosis presenting as Parkinsonism

“…[1,[3][4][5] It is common to find NCC lesions in the basal ganglia but, unlike our patients, clinical manifestation of these lesions is uncommon. [2] NCC presenting as parkinsonism has been previously reported in four cases. [3][4][5] There was brainstem cysticercotic ependymitis and midbrain encephalitis in three cases, but none reported direct involvement of basal ganglia by NCC.…”

“…[1] Movement disorders have been rarely described in association with NCC. [2] We report two cases of NCC presenting with features of parkinsonism.…”
