The introduction of modern neuroimaging and immunologic techniques has increased the diagnostic accuracy for neurocysticercosis.
However, there are some conditions that mimic neurocysticercosis by the time of the initial evaluation of the patient. We present six patients with a single abnormally dilated perivascular Virchow-Robin space mimicking a cysticercus.
In such cases, administration of repeated trials of cysticidal drugs together with long-term follow-up observation, excluded the diagnosis of neurocysticercosis. Physicians working in cysticercosis-endemic areas must keep in mind the possible occurrence of a single dilated perivascular space, to avoid the practice of unnecessary invasive procedures in patients with “cysticerci-like” lesions that do not change after several courses of cysticidal drug therapy.
