We report an intrahepatic portosystemic venous shunt (IPVS) detected by ultrasound in an asymptomatic newborn. The lesion, which was further documented using color Doppler ultrasound and magnetic resonance imaging (MRI), had almost totally disappeared 6 months later without any treatment. Intrahepatic portosystemic venous shunts (IPVS) are uncommon and their etiology is controversial. Some cases of IPVS have been reported in the literature, most of them in adult patients with portal hypertension and cirrhosis of the liver. However, only scattered reports describe IPVS in the absence of liver pathology. A revision of the proposed etiologies of IPVS is made and the usefulness of gray-scale and color Doppler sonography and MRI in diagnosing IPVS is discussed.
我们报告了一例通过超声在无症状新生儿中检测到的肝内门体静脉分流（IPVS）。该病变通过彩色多普勒超声和磁共振成像（MRI）进一步得到证实，6个月后未经任何治疗几乎完全消失。肝内门体静脉分流（IPVS）并不常见，其病因存在争议。文献中已有一些IPVS病例报道，其中大多数是患有门静脉高压和肝硬化的成年患者。然而，仅有零星报道描述了无肝脏病变情况下的IPVS。本文对IPVS的推测病因进行了综述，并讨论了灰阶超声、彩色多普勒超声及MRI在诊断IPVS中的作用。
