case_images: (a) Computed tomography scan showing midline depressed fracture compressing the SSS and causing bilateral posterior frontal venous infarctions, (b) MRI cervical spine showing normal study, (c) CT venography (preoperative) showing a defect in the SSS, (d) Bone window of the same CT venography image as in c showing the depressed bone fragment in the midline, (e) MRV done at 6 months follow-up showing filling of the SSS, (f) MRI scan of the brain in coronal section (posterior frontal region) showing resolved venous infarctions

case_images: Computerized tomography (CT) scan of the brain showed midline parietal depressed fracture with bilateral frontoparietal mixed density lesions and surrounding edema suggestive of venous infarction [Figure 1a-d]. CT venogram showed absence of filling of middle one-third of SSS under the depressed fracture fragment [Figure 1c]. CT and magnetic resonance imaging (MRI) of the cervical spine were normal [Figure 1b], thus ruling out a spinal cause for the quadriplegia. MRC grade 4/5 power in all four limbs. MRV imaging showed a patent SSS [Figure 1e], with areas of residual gliotic changes on both sides of the SSS [Figure 1f].
