case_images: Bilateral cerebral hemispheres, cerebellum, and diencephalon were symmetrical, with clear boundaries between gray and white matter, and no definite abnormal density shadow was observed in the brain parenchyma definite abnormality was found in the skull bone. The C4-5 segments of bilateral internal carotid arteries were hyperdense. The paranasal sinus mucosa was slightly thickened.

case_images: At 01:28, A reading of the CT film (Figure 1) showed no obvious signs of acute cerebral hemorrhage.
case_images: On T1 and T2 sequences, an abnormal signal is visible in the epidural space at the posterior part of the spinal canal from C2 to T1, which is suggestive of an epidural hemorrhage, with the spinal cord being compressed and displaced anteriorly and to the right. The red arrow indicates the site of the lesion.

case_images: A plain computed tomography (CT) scan showed a strip of high-density shadow in the posterior part of the cervical spinal canal, with a CT value of about 71 HU, and the spinal cord was slightly compressed and displaced in the right front. The site of the lesion is indicated by the red arrow.

case_images: The CT plain scan images suggested a strip-like high-density shadow at the posterior part of the spinal canal from C2 to C7 levels, with a CT value of approximately 71 HU, indicating slight compression and right anterior displacement of the spinal cord, suggesting the possibility of epidural hemorrhage (Figure 3). The CTA did not reveal any obvious arteriovenous malformations.
case_images: T2 showed a left epidural hematoma at the level of the C3-4 vertebral body, with reduced range and thickness of the lesion. The site of the lesion is indicated by the red arrow.

case_images: It revealed an epidural hematoma on the left side at the level of the C3-C4 vertebral bodies, with compression of the adjacent cervical spinal cord and the left nerve root and a reduction in the extent and thickness of the lesion compared to the previous one (Figure 4).
