[A case of dissecting aneurysm of the basilar artery extended from the top of the basilar artery to the proximal part].
A rare case of the dissecting aneurysm of the basilar artery is reported. A 48-year-old man was admitted to our hospital because of a sudden onset comatose state. An hour later he recovered consciousness with the residual disturbance of the vertical ocular movement. Computed tomogram on second day revealed low density lesions in the medial part of the bilateral thalamus, and the mesencephalic tegmentum and the cerebellar peduncle on the left side. Cerebral angiograms on the same day and 13th day showed a double lumen sign of the basilar artery and slight extension of the dissecting aneurysm, respectively. However, the cerebral angiogram 6 months after the onset revealed a little bit shrinkage of the aneurysm. The patient was treated conservatively and is in good condition with slight limitation of the downward gaze 10 months after the onset. We reviewed the clinical sign, cerebral angiogram, treatment and prognosis of the dissecting aneurysm of the basilar artery.
