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.
Clinical presentation: 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.
Intervention: 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.
Conclusion: Both patients manifested transient focal hyperemia of the spinal cord after acute decompression by resection of a spinal meningioma.
