Abnormal hyperdensity of intracranial blood vessels on non-contrast computed tomography scan (NCCT) may be found in cases with raised hematocrit. This finding not only simulates the appearance of a contrast enhanced CT scan but also may mimic dural venous sinus thrombosis. Here we report a case of child with Fallot's tetralogy and central cyanosis who showed abnormally hyperdense intracranial vessels on NCCT of head simulating the appearance of dural venous sinus thrombosis. The absence of suggestive clinical findings in the child, hyperdensity of intracranial arteries as well as the veins and a normal magnetic resonance venogram (MRV) suggested that the raised hematocrit is responsible for such appearance.
