Abstract:
Objective To investigate the imaging features of primary hepatic neuroendocrine carcinoma.Methods The imaging features of primary hepatic neuroendocrine carcinoma confirmed by pathology in 5 patients were reviewed retrospectively.Among the patients,plain and contrast enhanced CT in 4 and plain and contrast enhanced MRI in 1 were performed.Results CT showed a single lesion in 2 patients and multiple lesions in other 2 with the maximum diameter of 5.5 cm-10 cm.On plain CT,all lesions were hy-podensity with clear boundary and lower area in the center.The enhanced CT showed the lesions with obvious enhancement in arteri-al phase and gradually increasing enhanced area in portal vein and delayed phases but without enhancement in the lesion center.MRI showed the only one lesion in 1 patient with heterogenerous hypointensity on T1 WI,hyperintersity on T2 WI and DWI,and with mild to moderate delayed enhancement.The maximum diameter of the lesion was 5.0 cm,accompanied by a small round cystic structure at the periphery.The compression and displacement of peripheral blood vessels by the lesion without thrombus,and no lymphade-nopathy were also identified.Conclusion CT and MRI may show the imaging characteristics of the primary hepatic neuroendocrine carcinoma,which is helpful for the diagnosis of the tumor.
