title: Nonenhancing spinal subdural metastatic tumor.
abstract: We describe a case of a spinal subdural metastatic tumor that became rapidly symptomatic after a minor trauma, as a result of severe cord compression and cord hemorrhage. On MR imaging, the lesion was oval, hyperintense with a dark rim on T2-weighted fast spin-echo images, isointense to the cord on T1-weighted images, and had dark and bright areas on gradient-echo T2*-weighted images, consistent with a hyperacute-to-acute hematoma. The hemorrhagic tumor showed no evidence of contrast enhancement.
