The scans revealed significant bilateral intraventricular hemorrhage (IVH) involving the lateral, third, and fourth ventricles and basal cistern (Figures 1 and 2).
Computed tomography scan of the brain showing intraventricular hemorrhage involving the lateral third and fourth ventricles as well as the basal cistern with mild to moderate enlargement of the lateral ventricles.

The scans revealed significant bilateral intraventricular hemorrhage (IVH) involving the lateral, third, and fourth ventricles and basal cistern (Figures 1 and 2).
Magnetic resonance imaging of the brain showing intraventricular hemorrhage within the lateral third and fourth ventricles with hydrocephalus. Bilateral thalami and basal ganglia hemorrhage can be noted, primarily on the left side. Diffuse diffusion signal abnormality can be noted in the cerebral hemisphere, likely representing ischemic/necrotic changes.

Arterial angiography showed no flow in the intracranial arteries, and venous angiography showed no flow in dural venous sinuses suggestive of cerebral venous sinus thrombosis (Figures 3-5).

Arterial angiography showed no flow in the intracranial arteries, and venous angiography showed no flow in dural venous sinuses suggestive of cerebral venous sinus thrombosis (Figures 3-5).
Arterial and venous magnetic resonance angiography scans of the brain showing no intracranial arterial flow. No flow signal was identified in the dural venous sinuses, likely representing underlying sinus thrombosis.
