An Indian woman with multiple and nodular cerebral lesions presenting epithelioid granulomas was diagnosed as suspected malignant tumours and the biopsy was carried at local hospital in Japan. The specimen was pathologically diagnosed as tuberculoma. However, due to her nationality, the authors suspected it to be neurocysticercosis (NCC) and carried out serology and applied mitochondrial DNA analysis of Taenia solium. These diagnostic tools revealed it as NCC radiologically and pathologically mimicking central nervous tuberculomas. Molecular confirmation of NCC cases is strongly recommended when we can get the biopsy specimens.
