title: L5 radiculopathy caused by ossification of the ligamentum flavum: a case report.
abstract: We describe a case of ossification of the ligamentum flavum in the thoracolumbar junction presenting as an L5 radiculopathy. Magnetic resonance imaging revealed a hypodense lesion on T2-weighted image at the T10-T12 level causing the right dural sac compression, and electrodiagnostic findings were compatible with the right L5 radiculopathy. The location and cause of the compression were confirmed by a surgery. The clinical findings and electrodiagnostic features of such lesions located at the thoracolumbar spinal junction are discussed.
