The definitive diagnosis of neuro-invasive helminth parasites is a challenge for both clinicians and neuropathologists. Depending on the complexity and integrity of the organisms, as well as the presentation on the tissue section plane, the correct identification of the parasites may be complicated and is easily confused. However, prognosis, therapy, recognition of possible parasite reservoirs and prevention of future infections all depend on the specific diagnosis. With the application of molecular tools the identification is greatly facilitated, also from sophisticated material such as formalin-fixed and paraffin-embedded tissue samples. Here, several cases of CNS infections with histologically similar cestode and nematode parasites (Taenia solium, Taenia crassiceps, Echinococcus multilocularis and Halicephalobus sp., respectively) are presented which have been recently diagnosed molecularly in the human brain. The specific diagnosis revealed a totally different ecology and epidemiology despite very similar morphology.
