"Computed tomography-negative" intracerebral hemorrhage: case report and implications for management.

摘要: Background Noncontrast computed tomographic (CT) scanning of the brain is main imaging modality recommended for initial emergency evaluation acute stroke. The role CT in this setting to rule out intracerebral hemorrhage, especially subjects who are potential candidates thrombolytic therapy. Objectives and Results We studied a patient had symptoms suggestive transient ischemic attack. Although serial scans showed no evidence subacute hemorrhage was demonstrated by magnetic resonance imaging. Conclusions This case suggests that an alternative should be considered patients with stroke lower risk undetected being or anticoagulant There literature other "CT-negative" cases as well availability techniques such gradient echo ("susceptibility-weighted") sequences, which can enhance ability detect hemorrhage.
