A: Admission computed tomography (CT) scan showing minimal subarachnoid bleeding within the right middle temporal gyrus. B: At 6 hours CT development of a large right temporal contusion. Blood surrounding the contusion descends over the petrosal bone inside the cerebellopontine and cerebellomedullary cisterns, reaching the right lateral aspect of pons. C: Twenty-four hours CT, after worsening of symptoms. A volume increase of temporal contusion is observed (on the left). The same CT extended to the cervical spine. A large intradural clot is seen displacing the upper spinal cord to the left side (black arrows).

An initial computed tomography (CT) scan showed a small quote of subarachnoid hemorrhage within the middle temporal gyrus of the right temporal lobe (Fig. 1A). At 6 hours CT, a large, right temporal lobe contusion with minimal perilesional edema was observed (Fig. 1B). A new CT scan showed an increase of the temporal contusion (Fig. 1C, on the left). A large, intradural, right-sided blood clot occupied the upper spinal canal up to the third cervical vertebra, displacing contralaterally the brainstem and the upper spinal cord (Fig. 1C, black arrows).
A: Postoperative computed tomography (CT) showing no evolution of temporal contusion and the characteristics of bone opening (suboccipital craniectomy, C1-C2 laminectomy, C3 right hemilaminectomy). B: Three months postoperative magnetic resonance imaging (MRI) showing a small ischemic lesion within the right dorsal aspect of the spinal cord (black arrows). CT scan confirms full resorption of temporal contusion.

A 3-month follow-up MRI showed a small ischemic lesion within the right dorsal aspect of the spinal cord in T2-weighted sequences (Fig. 2B, black arrows). CT scan performed at the same time showed full resorption of the temporal lobe contusion (Fig. 2B).
