| 目的 与肝癌及肝腺瘤对比,观察肝血管周上皮样细胞瘤(PEComa)临床及CT表现。方法 回顾性分析30例肝PEComa及肝癌、肝腺瘤各31例,与肝癌及肝腺瘤对比,观察肝PEComa临床及CT表现。结果 肝PEComa组患者性别、年龄、症状,以及肝炎、肝硬化及甲胎蛋白(AFP)阳性占比均与肝癌组差异有统计学意义(P均＜0.05),患者性别及年龄与肝腺瘤组差异亦均有统计学意义(P均＜0.05)。肝PEComa组脂肪及畸形血管占比,强化方式、动脉期和静脉期对比增强率(CER)均与肝癌组差异有统计学意义(P均＜0.05);脂肪、包膜及畸形血管占比,以及强化方式、动脉期和静脉期CER亦均与肝腺瘤组差异有统计学意义(P均＜0.05)。结论 相比肝癌及肝腺瘤,肝PEComa多为良性且好发于女性,其CT表现具有一定特征性,有助于鉴别。 |

| 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. |
