Abstract:
Objective To observe the clinical and CT findings of hepatic perivascular epithelioid cell tumor(PEComa)compared with liver cancer and liver adenoma.Methods Thirty patients with hepatic PEComa,31 patients with liver cancer and 31 patients with liver adenoma were retrospectively enrolled.Compared with liver cancer and liver adenoma,the clinical and CT findings of hepatic PEComa were observed.Results Significant differences of patients' gender,age and symptoms,also of the proportion of hepatitis,cirrhosis and positive alpha fetoprotein(AFP)were found between hepatic PEComa group and liver cancer group(all P＜0.05),while of patients' gender and age were found between hepatic PEComa group and liver adenoma group(both P＜0.05).Significant differences of the proportion of fat and malformed blood vessels,enhancement mode,as well as contrast enhancement ratio CER of arterial and venous phases were noticed between hepatic PEComa group and liver cancer group(all P＜0.05),while of the proportion of fat,capsule and malformed blood vessels,as well as enhancement mode and CER of arterial and venous phases were noticed between hepatic PEComa group and liver adenoma group(all P＜0.05).Conclusion Compared with liver cancer and liver adenoma,hepatic PEComa was mostly benign and more common in women,with somewhat characteristic CT findings being helpful to differential diagnosis.
