(a) Sagital T2-weighted magnetic resonance imaging (MRI) showing well-defined hyperintense lesions at many levels in the thoracic spinal cord. B-C Axial T2-weighted MRI, showing the intradural extramedullary location of the lesions, compressing the anterior (b) and lateral spinal cord (c).

T4 sensory level to pin appreciation. The thoracic magnetic resonance (MR) imaging revealed multiple intradural extramedullary cystic lesions at the T4-6 and T9-11 levels [Figure 1].

At the T4-T6 levels, once the dura was opened, 12 cystic lesions of different sizes protruded through the arachnoid gap and were removed along with the arachnoid membrane [Figure 2].
Hematoxylin and eosin staining indicated an eosinophilic outer cuticle layer and a single-layered sub-cuticle cell, representing typical cysticercosis findings, at magnification (a) x100 and (b) x50.

The histopathological report confirmed spinal NCC [Figure 3].
Postoperative T2-weighted magnetic resonance imaging. (a) Sagittal view showing the signal intensity of cerebrospinal fluid without septations in the upper thoracic level and partial resolution in the low level. (b and c) Axial view with a resolution of the compression in the upper level (b) and persistence of the cysts in the low level.

In addition, corticosteroids were continued for the next 3 months to reduce inflammation [Figure 4].
