Objective To investigate the CT features of primary hepatic neuroendocrine carcinoma (PHNEC). Methods CT finding of 6 cases with PHNEC proved by pathology were analyzed retrospectively, all were performed plain and dynamic enhanced CT scanning. Results ① Of the 6 cases, 3 cases showed single lesion, and 2 cases in the right lobe, 1 case in the left lobe. 3 cases of multiple, showed single large tumor with multiple nodules .Tumor diameters were 1.8-8.5 cm. ② CT findings: All had no cirrhosis background, CT scan showed solid density lumps or nodules with clear boundary. Dynamic enhanced scan: 5 cases inhomogeneous significantly enhanced at arterial phase, and 3 cases continued to strengthen with uneven slightly density, 2 cases dissected with low density at portal venous phase. 1 case of solitary lesions slight enhanced at arterial phase, continued to strengthen at portal venous phase, showed relatively low density at delay period. Conclusion The CT findings of PHNEC had certain characteristics, usually showed hepatic single low-density mass or a large mass with multiple Nodules, Most tumors significantly enhanced at arterial phase, continued to strengthen at portal phase, a few showed mild to moderate persistent enhancement, CT exam was useful for the diagnosis before surgery.
