case_images: (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.

case_images: Enhanced MRI with gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA) showed homogeneous enhancement without a dural tail sign (Figure 1).
case_images: (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.

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

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

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

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