  • Look Inside

We present a rare case of a dissecting aneurysm of the left anterior cerebral artery (ACA) with persis-tent pearl & string sign on cerebral angiograms over a period of 8 years. A 43-year-old woman with dis-turbance of consciousness and right sided hemiparesis was conservatively treated. Computed tomographic(CT) scan revealed a low-density area in the left frontal lobe. Initial angiography, which was performed at6 months after the onset, showed a pearl & string sign at the A2 portion of the left ACA. After 8 years, re-peat angiography again showed persistent pearl & string sign at the same portion of the left ACA. We dis-cussed the changes in findings usually obtained in cerebral angiography concerning dissecting aneurysmsin ACA.
