Magnetic resonance imaging of the cervical spine suggestive of (a and b) T2 hyperintense extradural C7 cystic lesion causing severe cord compression with a displacement of the spinal cord to the right. (c) The cyst wall enhanced with the administration of gadolinium.

It was hyperintense on the T2-weighted MR study, and the cyst wall enhanced with the administration of gadolinium [Figure 1].
(a) Intraoperative photograph showing a cervical extradural ganglion cyst with severe cord compression. (b) The cyst contains gelatinous material. (c) After complete excision of the cyst, the spinal cord is well decompressed.

Notably, there was no obvious communication with the left C7-T1 facet joint cavity [Figure 2].
(a) Hematoxylin and eosin x40 magnification: a low power view showing a part of the fibrous cyst wall without a discernible internal lining. Mucoid and basophilic calcified material is seen. (b) Alcian blue - Periodic Acid Schiff (PAS) x40 magnification: highlights the mucoid material in the lumen of the cyst. (c) Alcian blue - PAS x100 magnification: another area showing myxoid degeneration in the cyst wall, consistent with a ganglion cyst.

This, accompanied by myxoid degeneration within the cyst wall, was consistent with a diagnosis of a ganglion cyst [Figure 3].
