We report a patient with multiple angiographically occult vascular malformations in the brain and spine. Magnetic resonance imaging showed multiple lesions in brain and spine with hypointense areas on both T1 and T2-weighted images. These hypointense areas are usually secondary to hemosiderin deposits consistent with remote bleeding in the lesions. We conclude that when magnetic resonance reveals an intraspinal lesion with signal intensity characteristics consistent with a vascular malformation, an examination of the brain should be performed to rule out associated intracranial lesions. The finding of multiple lesions in the brain with identical signal intensity characteristics reinforces the diagnosis of vascular malformation.
我们报告了一名患有脑部和脊柱多发血管造影隐匿性血管畸形的患者。磁共振成像显示脑部和脊柱有多个病变，在T1加权和T2加权图像上均为低信号区。这些低信号区通常继发于含铁血黄素沉积，与病变内既往出血一致。我们得出结论，当磁共振显示脊髓内病变具有与血管畸形一致的信号强度特征时，应进行脑部检查以排除相关的颅内病变。脑部发现多个具有相同信号强度特征的病变强化了血管畸形的诊断。
