Transient focal spinal cord hyperemia after resection of spinal meningioma: case report.
OBJECTIVE
Transient postoperative focal hyperemia in the spinal cord is rare. We report 2 patients with transient focal hyperemia after the resection of a spinal meningioma that led to temporal neurological deterioration followed by complete recovery.


METHODS
Two patients presented with cervical meningiomas at the C7 and C1-C2 levels. Preoperatively, both patients experienced gradual exacerbation of spastic tetraparesis. Magnetic resonance imaging revealed isointensity on T1-weighted images and high intensity on T2-weighted images with homogeneous enhancement.


METHODS
Both patients underwent complete tumor removal. A histopathological examination revealed a meningothelial meningioma in both patients. Postoperative magnetic resonance imaging revealed transient focal hyperemia of the cervical cord.


CONCLUSIONS
Both patients manifested transient focal hyperemia of the spinal cord after acute decompression by resection of a spinal meningioma.
