OBJECTIVE
To present findings on computed tomography scans of the chest indicative of extramedullary hematopoiesis in six patients.
METHODS
We retrospectively analyzed computed tomography scans of six adult patients - five males and one female - with a mean age of 36.5 years. Two radiologists independently reviewed the scans, and a consensus was reached in discrepant cases.
RESULTS
The most common finding in the scans was lower paravertebral masses with heterogeneous content (four patients). The scans of two patients showed a solitary parietal and pleural mass.
CONCLUSIONS
There are findings in computed tomography scans that are highly suggestive of extramedullary hematopoiesis, especially when those findings correlate with underlying blood diseases. Such findings, in most of the cases, allow physicians to dispense with histopathological confirmation.
目的
呈现6例提示髓外造血的胸部计算机断层扫描结果。
方法
我们回顾性分析了6例成年患者（5例男性，1例女性）的计算机断层扫描，平均年龄为36.5岁。两名放射科医生独立阅片，在存在分歧的病例中达成共识。
结果
扫描中最常见的发现是椎旁下部有密度不均匀的肿块（4例患者）。2例患者的扫描显示有单个顶叶和胸膜肿块。
结论
计算机断层扫描结果高度提示髓外造血，尤其是当这些结果与潜在血液疾病相关时。在大多数情况下，这些结果可使医生无需进行组织病理学确认。
