Objective:
To report the clinical and radiologic findings in a case of transient minimally conscious state after rupture and coiling of a giant basilar aneurysm.
Design:
Case report.
Setting:
Neuroscience intensive care unit.
Patient:
A 44-year-old man who developed a transient minimally conscious state in association with perianeurysmal edema in the rostral brainstem and thalamus after rupture and coiling of a giant basilar artery aneurysm.
Main Outcome Measure:
Correlation of clinical and magnetic resonance imaging findings.
Results:
A minimally conscious state and bilaterally symmetric vasogenic edema of the rostral brainstem and thalamus developed 2 days after endovascular aneurysm coiling. The clinical and radiologic abnormalities improved significantly and in parallel during the following 4 weeks.
Conclusions:
Perianeurysmal vasogenic edema in the brainstem and thalamus can develop after rupture and coiling of a giant basilar artery aneurysm. This process can be transient and can produce dramatic alterations in consciousness that later resolve.
