Abstract:
Objective To discuss and analyze the imaging features of extramedullary hematopoiesis (EMH).Methods Imaging data of EMH in 7 patients with 85 lesions confirmed by clinical and pathological results were retrospectively analyzed.Results CT or MRI showed thoracic paravertebral multiple tumor-like soft tissue masses in 6 patients accompanied with pleural mass in 1,with liv-er mass in 1 and spleen mass in 1,and the masses in the distal ileum and in front of the inferior vena cava in 1.Thoracic paraverte-bral and pleural masses presented isodensity on plain CT and moderate enhancement on post-contrast CT.Among the 6 liver mas-ses,CT showed uniform density in 5 and small area of necrosis in 1.The only one spleen mass also appeared inner necrosis and mul-tiple small calcifications.The mass in the ileum presented thickened bowel wall with moderate enhancement,meanwhile the mass in front of vena cava presented obvious edge enhancement.MRI in 2 patients showed the masses with low signal on T1 WI and high sig-nal on T2 WI.Conclusion EMH has certain specific imaging characteristics,which may be helpful for correct diagnosis of EMH when combined with the clinical data.
