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].
