Magnetic resonance images of the left temporal lobe lesion. (a) Contrast-enhanced coronal T1-weighted image, showing rim-enhancing left temporal lobe lesion. (b) Axial T2-weighted image showing the same lesion with mild surrounding vasogenic edema.

MRI of the brain further delineated this as a solitary ring-enhancing lesion measuring 1.2 by 1 centimetre (Figure 1).
Histologic features of the resected left temporal lobe lesion. Fibrous cyst wall lined by aggregates of epithelioid histiocytes and multinucleated giant cells, along with necrosis and a mixed inflammatory infiltrate in the adjacent area (H&E, original magnification 200x).

Features characteristic of a cysticercus were absent, and no viable larva was identified (Figure 2).
Amplicons from Taenia solium-specific PCR (pTsol9 repeat element) after capillary electrophoresis. Lanes NT, NP, and M represent no template, negative patient, DNA size marker. Lane BT represents brain tissue and shows multiple bands of  120 bp, 280 bp, and 440 bp, corresponding to the amplification of 1, 2, and 3 repeat unit(s) of the pTsol9 element, respectively.

Capillary electrophoresis on QIAxcel  Advanced System (Qiagen, Hilden, Germany) equipped with DNA Fast Analysis Kit displayed multiple bands of expected sizes (120 bp, 280 bp, and 440 bp), corresponding to the amplification of 1, 2, and 3 repeat unit(s) of the pTsol9 element, respectively (Figure 3) and a single band of 810 bp for the 16S rRNA-12S rRNA genes.
