title: Gadolinium-DTPA enhancement of a recurrent intramedullary ependymoma: a case report.
abstract: Magnetic resonance images enhanced with the paramagnetic contrast agent gadolinium-DTPA accurately differentiated a recurrent intramedullary spinal cord ependymoma from surrounding postoperative and postirradiation spinal cord tissue changes, thereby facilitating total excision of the lesion. The illustrative case and the merits of enhanced magnetic resonance imaging are presented.
