Abstract

Objective To investigate the CT features of primary hepatic neuroendocrine carcinoma(PHNEC). Methods Unenhanced and dynamic contrast-enhanced CT of 7 patients with pathologically confirmed PHNEC was analyzed retrospectively.Results Of 7 patients without liver cirrhosis, the tumors were solitary(3) in the right lobe(2) and left lobe(1), or single large lesion with multiple satellite nodules(4). On CT, 5 lesions were low-density masses or nodules with well-defined boundary and heterogeneous marked contrast enhancement in the arterial phase progressively enhancing(3) or washing out in the portal venous phase(2). The remaining 2 solitary lesions enhanced slightly in the arterial phase continuing into the portal venous phase and washing out in the parenchymal phase. Conclusion CT features can aid pre-operative diagnosis of PHNEC.
