Sagittal MRI sections passing through the left neural foramina of the cervical and upper thoracic spine demonstrate a well-defined cystic lesion with a thin and regular wall at C7-T3 level. The cyst is following cerebrospinal fluid signal intensity on T1-weighted (a), T2-weighted (b), and short tau inversion recovery (c) images. There is no evidence of enhancement on contrast-enhanced T1-weighted image (d). Prominent neural foraminal widening at T1-T3 levels is visible in all images

It did not enhance following contrast administration (Fig. 1) and showed no restriction of diffusion on diffusion-weighted images and ADC mapping (Fig. 2).
Consecutive axial T2-weighted MRI sections through T2-T3 intervertebral disc level demonstrate the dural communication site of the extradural cyst with the spinal subarachnoid space. A signal-free area that is assumed to be the result of jet flow through the communicating pedicle is visible (arrow). Note the prominent widening of the left neural foramen

MRI sections through the T2-T3 intervertebral disc level demonstrated the dural communication site of the extradural cyst with the spinal subarachnoid space (Fig. 3). MR myelography precisely delineated the extension of the cyst (Fig. 4).
MR myelography clearly delineates the location, the size, and the extension of the cyst
