%X <B>UNASSIGNED: </B>Giant cell tumor of the tendon sheath (GCTTS) is commonly seen in the appendicular skeleton, and rarely arises from the axial skeleton. We describe a rare case of GCTTS in an adolescent in the upper cervical spine.<BR><B>UNASSIGNED: </B>A previously healthy 16-year-old boy presented with a 6-month history of numbness of right upper extremity, and had experienced a neck pain 4 months ago. Spinal MRI demonstrated a small syrinx at C2 level and a well-circumscribed extradural mass with contrast enhancement extending from the posterior arch of C1 to C2. The extradural mass was totally resected, and the syrinx underwent clinical and imaging surveillance.<BR><B>UNASSIGNED: </B>GCTTS should be considered in the differential diagnosis of the axial skeletal lesion although very rare. Gross-total resection is advocated in GCTTS of the upper cervical spine, and subtotal resection with meticulous lesion monitoring should be performed in unresectable cases.
