(A and B) Pre-operative T1W axial and T2W sagittal images reveal hyperintense bilateral retro- and supra- cerebellar subacute subdural hematoma, thickness of 2.09 cm and fourth ventricular and aqueduct compression with hydrocephalus. (C) T1W axial image shows ventriculomegaly. (D) Post op computed tomography (CT) scan demonstrating complete evacuation and improved mass effect on 4th ventricle.

Brain MRI (Figure 1A-C) showed bilateral cerebellar convexity T1WI and T2WI hyperintense hematoma measuring 2cm with supracerebellar and periaqueductal extension. Control CT scan (Figure 1D) done on 3rd post-op day showed complete evacuation of the hematoma and improvement of the hydrocephalus.
