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.
