Imaging Analysis of Intrathoracic Tumor-simulating Extramedullary Hematopoiesis / 实用放射学杂志

ABSTRACT

Objective To improve the accuracy of imaging diagnosis of intrathoracic tumor-simulating extramedullary hematopoiesis(EMH).Methods The chest radiographs and CT findings in two cases of intrathoracic tumor-simulating EMH with thalassemia were analyzed respectively and some related literatures were reviewed.Results A conventional chest X-ray showed rotundity or lobulated masses in the posterior inferior mediastinum in two cases, and CT scans showed smoothly marginated , homogeneous, lobulated paravertebral masses, on enhanced CT scans, the masses showed mild homogeneous enhancement.Conclusion Although intrathoracic tumor-simulating EMH is short of typical imaging features, the combination of clinical ,laboratory and radiological findings could make the diagnosis of intrathoracic tumor-simulating EMH, so unnecessary treatment or surgery could be avoided.
