90. A 22-year-old man is brought to the emergency department after a fight during which he received a knife wound to his neck. The patient is in moderate distress but is alert and can follow commands. Vital signs are stable. Neurologic examination shows right-sided hemiplegia. Loss of proprioception and vibratory sensation is present below the C8 dermatome on the right side. On the left side, there is loss of pain and temperature sensation below the T2 dermatome. MRI of this patient's spine will most likely reveal which of the following?
