杂志文章abstract::Cervical spinal epidural hematoma is a rare cause of acute neurologic syndromes including paralysis of various types. Although devastating, it can be successfully treated surgically if recognized early. We report two cases of spontaneous cervical epidural hematoma diagnosed by computed tomography, the first with a pla...
