Abstract:
Objective To correlate CT findings of secondary hepatic lymphoma with pathology and to evaluate it's clinical value.Methods Nine patients with secondary hepatic lymphoma confirmed by pathology underwent spiral CT scanning and dual-phase dynamic contrast-enhancement scanning before operation, the CT data were reviewed and analysed retrospectively in comparison with surgical and pathological results.Results Twenty-three lesions of secondary hepatic lymphoma in 9 patients were located in the left lobe (9 lesions), the fight lobe (6 lesions),the porta of the liver (5 lesions) and the caudate lobe (3 lesions), respectively.Sixteen of these 23 lesions were distributed over an area near the portal vein, 7 were seattered in the exterior of liver.17 lesions had an ellipsoid contour and 6 showed irregular contour.The diameter of the lesions ranged from 2.7 to 16.5 cm, with a mean diameter of 5.9cm.The tumor demonstrated mild homogeneous dynamic delayed contrasted-enhancement and the CT value of the non-contrast scans, AP phases and PVP phases were 20.7 to 31.5 HU(with a mean value of 25.3 HU), 23.8 to 48.5 HU(with a mean value of 31.9 HU) and 35.3 to 60.2 HU(with a mean value of 47.8 HU) respectively.Intrinsic hepatic vessels could be discerned in 6 lesions.The lesions situated in the perta of the liver encased the portal vessels, but there was no vessel compression or occlusion.Conclusion Recognition of the dynamic CT features of hepatic lymphoma could enhance its diagnostic accuracy.
