case_images: Follow-up computed tomography performed 2 days after the accident. (A) Slight pneumothorax, subcutaneous emphysema, pneumomediastinum, and first rib fracture of the right chest. (B) Spinal computed tomography image demonstrating air in the right C7/Th1 intervertebral foramen and subdural space of the spinal canal. (C) Intracranial air accumulating in the frontal or subarachnoid space and ventricles. (D) Sagittal images showing subarachnoid air around the spinal cord (arrow) and pneumocephalus.

case_images: Air was also detected in the right C7/Th1 intervertebral foramen and subdural space of the spinal canal (Figure 1A-D) An 8 Fr. chest tube was inserted and placed under the water sealing management, and the prophylactic antibiotics was not administered to the patient to prevent meningitis.
case_images: (A) Brain computed tomography revealing rapid absorption of intracranial air the day following initiation of chest drainage. (B) Spinal magnetic resonance imaging showing hyperintense lesions (dotted circle) around the right C7/Th1 intervertebral foramen on T2-weighted images. (C) Computed tomography myelography revealing a pseudomeningocele in the same region.

case_images: The day after initiating chest drainage, brain CT revealed a rapid reduction in intracranial air (Figure 2A). Although the patient had no symptoms of cerebrospinal fluid (CSF) leakage, such as headache or loss of consciousness, spinal magnetic resonance imaging (MRI) revealed hyperintense lesions around the right C7/Th1 intervertebral foramen on T2-weighted images, suggesting CSF leakage and nerve root avulsion (Figure 2B,C).
