Coronal view along the plane of the choroid plexus of sonogram (a) showed obstructive hydrocephalus with enlarged bilateral lateral ventricle and high echogenicity over the quadrigeminal cistern and cerebellar hemispheres (arrow). Midline sagittal view of sonogram (b) showed enlarged 3rd ventricle and ill-defined hyperechoic density over the cerebellum (arrow) with upward compression of the 3rd ventricle and the 4th ventricle hard to identified

The coronal view along the plane of the choroid plexus and the midline sagittal view through the anterior fontanel [Figure 1] revealed obstructive hydrocephalus with enlarged bilateral lateral and 3rd ventricles and ill-defined hyperechoic density over the cerebellum with upward compression of the 3rd ventricle and the 4th ventricle hardly to identified.
Axial view of cranial magnetic resonance imaging. A large hematoma shadow (arrow) in the region of the left cerebellar hemisphere as mixed iso-signal intensity and part of high signal intensity on T1 fluid-attenuated inversion recovery (a) mixed iso-signal intensity with small faint low signal intensity and marginal rim low signal intensity on T2 fluid-attenuated inversion recovery (b) and diffusion-weighted imaging (c) low signal intensity on apparent diffusion coefficient (d) small focal hemorrhage in the left cerebellar hemisphere was suspected. T1 fluid-attenuated inversion recovery (a) showed high signal intensity and T2 fluid-attenuated inversion recovery (b) showed low signal intensity along the course of bilateral transverse sinuses (arrowhead), suspicion of sinus thrombosis

Magnetic resonance imaging (MRI) of the head [Figures 2 and 3] was soon arranged and revealed a subdural hematoma in the region of the left cerebellar hemisphere causing compression and displacement of the 4th ventricle and resulted in obstructive hydrocephalus with dilatation of the lateral and 3rd ventricles.
Axial T1 fluid-attenuated inversion recovery (a) showed hydrocephalus with dilatation of the 3rd ventricle and lateral ventricles. Sagittal T1 fluid-attenuated inversion recovery (b) showed displacement of the 4th ventricle with dilatation of the 3rd ventricle
