case_images: Preoperative MRI. (a) Sagittal section, C+ T1WI showing a nonenhanced iso-hyperintense epidural mass compressing the thecal sac from behind. Note the edema of the paravertebral soft tissues and the straightening of the cervical spine from antalgic contracture. (b) Sagittal section, T2WI showing hypointense signal of the lesion. (c) Axial section, T2WI showing T1-T2 foraminal extension of the lesion.

case_images: After 3 days of essentially normal investigations, a magnetic resonance imaging (MRI) of the cervicodorsal spine [Figure 2] revealed an extramedullary blood collection at C7- T2 level, extending craniocaudally for about 35 mm, within the left posterolateral portion of the vertebral canal, displacing the medullary cord to the right.
case_images: Postoperative MRI. Sagittal section, T2WI showing no further bleedings and a realigned medullary cord. Note the partial restoration in cervical lordosis.

case_images: A check-up MRI performed on postoperative day 4 [Figure 3] ruled out further bleedings and demonstrated realignment of the medullary cord.
case_images: Histological findings. Note the architecture of the lesion, made up of multiple closely packed vascular channels lined with endothelium within a fibrous stroma, with signs of hemorrhage.

case_images: Histopathological examination of the specimens was compatible with the diagnosis of a hemorrhagic CM [Figure 4].
