Abstract
We present a rare case of a cervical ganglion cyst. An 81-year-old woman with a 10-month history of neck pain was admitted with deterioration of left hand function, numbness in the legs and gait disturbance. Physical examination showed hyperreflexia with scapulohumeral reflex and muscle weakness especially in her left side. Magnetic resonance imaging revealed an intraspinal extradural mass at C1 level with extension of cystic lesion to C2 level compressing the spinal cord. C1-level mass showed low intensity on T1 and T2-weighted images. C2-level cystic mass showed low intensity on T1-weighted images, high intensity on T2-weighted images and rim enhancement on Gd-enhanced T1-weighted images. The cyst had a yellowish gelatinous content. C1-level mass was pathologically degenerative fibrocartilagenous tissue with chondrometaplasia. This case was diagnosed as an intraspinal ganglion cyst accompanied by pseudotumor.
