(A-F): A The initial plain CT scan on December 12 showed a cerebral contusion and laceration in bilateral frontal lobes and an intracerebral haematoma in left frontal lobe; B Plain CT scan on December 23 showed high-density thrombosis in the left transverse sinus; C Plain CT scan on December 23 revealed thrombosis in the sinus confluence and straight sinus, cerebral parenchymal infarction in the left parieto-occipital lobe, swelling of the left hemisphere, and compression of the left ventricle; D CT venography of December 23 showed absence of flow-related enhancement in the superior sagittal sinus, confluence of sinuses, and bilateral transverse sinuses, suggesting venous sinus thrombosis with open peripheral collateral vessels. E Plain CT scan on December 29 showed progression of the low-density lesion of the left parietotemporal occipital lobes and obvious brain swelling. F MRI on January 24 showed a patchy infarct lesion in the left parietal lobe and improvement of the surrounding brain swelling. The white solid arrows show the lesions
