Spinal MRI and histopathology of Case 1. Spinal MRI demonstrated an intramedullary lesion (arrowheads) at the T11-T12 levels, which showed hypo- to isointensity on T1-weighted imaging (A) and a mushroom-like hyperintense mural nodule on T2-weighted imaging (B). After the administration of contrast medium, ring-like contrast enhancement was noted (C-E). Photomicrograph of the histological specimen reveals cyst wall remnants of cysticercosis (F; ×100). Postoperative T1-weighted (G), T2-weighted (H), and contrast-enhanced (I) imaging showed that the isolated lesion was completely resected
