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

Figure 2

MRI work-up (a-b) at acute phase and delayed (7 months) MRI follow-up examination (c) of patient 1. (a) Axial transverse T2-weighted fast-spin echo (FSE) view through cingulate gyri demonstrating similar findings as in previous patient: oedema-related strong hypersignal intensity within them on both sides (black arrows). (b) Axial transverse diffusion-weighted ( factor = 1000 s/mm2) view in similar slice location (black arrows) failed to reveal hypersignal intensity, thereby excluding ischaemic cytotoxic damage. Only false positive artifacts due to adjacent hematoma were seen (white arrows). (c) Coronal T2-weighted FSE MR view at chronic phase (7 months) showed intrinsic textural integrity of the cingulate gyri. Meningeal hemosiderosis surrounding cingulate gyri featured by pial strong hyposignal intensity was present (arrows).
