A 49-year-old female with subacute myelopathic symptoms due to thickened cervicothoracic yellow ligament and abnormal epidural fibrous tissue is reported. Myelography showed a complete block at the Th3 level. Magnetic resonance imaging demonstrated an extra-axial mass lesion in the spinal canal at the cervicothoracic junction causing the spinal cord compression. Laminectomy with resection of the lesion resulted in good neurological recovery. Histological examination revealed a thickened ligamenta flava and abnormal epidural fibrous tissue without calcification foci.
