[Terson's syndrome which arose from ruptured right superior cerebellar artery aneurysm: a case report and 32 series investigations].
The case reported here was a 50-year-old woman with the onset of generalized convulsions and vomiting on November 22, 1993. At admission, her neurological sings and symptoms were classified as Hund & Hess grade IV, and precise examination revealed subarachnoid hemorrhage by rupture of aneurysm at the branching of the right superior cerebellar artery. Thus neck clipping was performed on the same day. Although her consciousness level gradually improved after operation, she complained of left vision disturbance on December 5 (14 days after onset). The visual acuity of the left eye was manual valve of 30 cm. It was precisely examined using fundoscopic examination and B mode ultrasonography making the diagnosis of left vitreous hemorrhage (Terson's syndrome). The visual acuity of the left eye began to improve on December 12, and was found to be 1.0 on November 18, 1994, about 1 year after onset. The hemorrhage was also determined to be almost completely absorbed by fundoscopic examination. In this report, the results of statistical analysis of 32 previous cases, in addition to our case, are described, together with the discussion on the pathogenesis of Terson's syndrome.
