PURPOSE
To describe the in vivo CT appearance of acute intracerebral blood clots formed from anemic platelet-depleted blood.
METHODS
Three patients with intracerebral hemorrhage secondary only to thrombocytopenia were examined with CT within 2 1/2 hours after the onset of clinical symptoms.
RESULTS
There were no unusual CT features found in the intracerebral hemorrhages of patients with only thrombocytopenia. Specifically, a hyperdense zone(s) surrounded by areas of decreased density was identified.
CONCLUSION
Clot retraction (which cannot occur in patients with severe thrombocytopenia) is not necessary for the CT appearance of acute intracerebral hemorrhage.
目的
描述由贫血且血小板减少的血液形成的急性脑内血凝块的体内CT表现。
方法
对3例仅因血小板减少继发脑出血的患者在临床症状发作后2.5小时内进行CT检查。
结果
仅血小板减少患者的脑内出血未发现异常CT特征。具体而言，发现了一个由密度降低区域包围的高密度区。
结论
急性脑内出血的CT表现并不需要凝块退缩（严重血小板减少患者不会发生凝块退缩）。
