(a) T2-weighted sagittal MRI of the cervical spine showed a tumor in the craniocervical junction. (b, c) MRI followed by the intravenous administration of gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) showed a homogeneously enhanced intradural tumor without obvious dural tail sign.

Enhanced MRI with gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) showed homogeneous enhancement without a dural tail sign (Figure 1).
(a) Right vertebral angiogram demonstrating tumor staining, supplied by the right C2 (arrow) and C3 (arrowhead) segmental arteries. (b) A right vertebral angiogram after embolization using a coil showing slight tumor staining.

An angiogram after embolization showed a decreased tumor stain (Figure 2).
(a) A mass was identified after durotomy (arrowhead). (b) The tumor was resected in a piecemeal fashion.

Resection was carefully performed via central debulking with piecemeal resection to avoid neurological damage under spinal monitoring (Figure 3).
The resected tumor was composed of numerous blood vessels and intervening tumor cells. The blood vessels were variably hyalinized and thick-walled.

Some whorls and psammoma bodies were present (Figure 4).
(a, b) T2-weighted sagittal and axial MRI at one year after surgery showed no obvious recurrence.

MRI obtained one year after surgery revealed decompression of the spinal cord and no sign of recurrence (Figure 5).
