case_images: (a) Axial computed tomography (CT) image shows subarachnoid hemorrhage in the peri-mesencephalic and interpeduncular cisterns (arrows). (b) Axial CT image of the same patient shows significant dilatation of the ventricular system consistent with hydrocephalus. Minimal intraventricular hemorrhage (arrowhead) is also noted layering in the occipital horns of the right lateral ventricles, which are significantly dilated.

case_images: An urgent brain computed tomography (CT) scan showed a non-aneurysmal subarachnoid hemorrhage [Figure 1a] associated with a tetraventricular non-communicating HC [Figure 1b].
case_images: (a) Axial contrast-enhanced computed tomography (CT) image shows homogeneous collections (asterisks) with thin contrast-enhancing walls (arrows) in the anterior peritoneal cavity. The ventriculoperitoneal shunt distal catheter is also visible (arrowheads). (b) Reformatted coronal contrast-enhanced CT image shows homogeneous collections (asterisks) with contrast-enhancing walls (arrows) adjacent to the gastric wall (arrowheads).

case_images: A contrast-enhancement CT scan showed abscess collections and pseudocysts in the mesogastrium [Figure 2a] and in the pelvic cavity [Figure 2b] with diffuse peritoneal hyperattenuation.
