title: Magnetic resonance imaging of intradural lumbar disc herniation.
abstract: The case of a 62-year-old patient with intradural lumbar disc herniation diagnosed by magnetic resonance imaging (MRI) and verified by surgery is reported. The patient presented with low back pain. T(1)-weighted MRI demonstrated an intradural iso-intensity mass at the L2/3 level without obliteration of the extradural fat space. Gd-DTPA enhanced MRI showed a beak like mass with rim enhancement except at its ventral surface. Intraoperative findings disclosed an intradural epiarachnoid fragmented disc which was covered by venous plexus. Copyright 1999 Harcourt Publishers Ltd.
