A 77-year-old woman with a history of valvular heart disease, atrial fibrillation and a massive infarction in the right cerebral hemisphere developed contralateral infarction due to occlusion of the internal carotid artery. A string-like structure with higher density than normal brain was demonstrated on non-enhanced computed tomography that was performed in the acute stage. This abnormal structure seen in the left hemisphere was thought to be consistent with the middle cerebral artery trunk of the affected side. Seventeen days after the onset, the abnormal structure was no more visuslized on non-enhanced CT.<BR>These findings suggested that the abnormal structure with increased density was compatible with thromboembolus or intraluminal clot formed in the distal part of the occluded internal carotid artery. An importance of this finding as a diagnostic sign of the cerebral arterial occlusion was discussed.
