title: Ocular motor paralysis and arachnoid cyst.
abstract: Four days after a 32-year-old woman was hit in the right eye with a racquetball, a paralysis of the right third nerve developed. Computerized axial tomography with metrizamide demonstrated an arachnoid cyst in the interpeduncular fossa. After the cyst was surgically decompressed, the third-nerve paralysis cleared.
