Case Report

Reversible Akinetic Mutism after Aneurysmal Subarachnoid Haemorrhage in the Territory of the Anterior Cerebral Artery without Permanent Ischaemic Damage to Anterior Cingulate Gyri

Figure 1

Admission brain CT scanner work-up of patient 1. (a–c) Serial unenhanced axial transverse views through the level of the corpus callosum showing massive hyperintense subpial hematoma at the cranial border of the corpus together (white arrows) with a mild SAH at the lateral borders of the frontal and parietal lobes, mainly on the left side. (d) Contrast-enhanced mid-sagittal reformatted Maximum Intensity Proton (MIP) view showing severe polylobulated impingement of the subpial hematoma (white arrows) on the corpus callosum (asterisks) and the causative microaneurysm on the left ACA (arrowhead). Note artifactual lowering of the apparent density of the hematoma because of changes in image scaling (window/level) after contrast agent injection.
