Subarachnoid hemorrhage (SAH) is one of the most common radiological features of traumatic brain injury (TBI) occurring in 30%–40% of moderate–severe head injuries.Vasospasm and resulting cerebral ischemia as well as cerebral hyperemia can cause delayed neurological recovery and poor outcome. A clinical deterioration in Glasgow Coma Scale score without an accompanying radiological worsening is suggestive of vasospasm. However, hyperemia could be another possibility which can easily be considered with corroborating transcranial Doppler (TCD) features. We illustrate a case where differentiating the two entities enabled a good neurological recovery........
