Hepatic portal venous gas (HPVG) is a rare imaging finding in infants and usually indicative of a severe disease process such as necrotizing enterocolitis, bowel ischemia, or bowel wall rupture / infarction. The diagnosis of HPVG may have serious implications such as parenteral nutrition, antibiotics and even surgery. In this case, we present an 8-week-old male with a history of prematurity presenting with HPVG, later concluded to be caused by milk protein allergy. Milk protein allergy is a rare cause of HPVG, but it should be recognized due to its benignity and potential prevention of unnecessary testing and interventions.
肝门静脉积气（HPVG）在婴儿中是一种罕见的影像学表现，通常提示存在严重的疾病过程，如坏死性小肠结肠炎、肠缺血或肠壁破裂/梗死。HPVG的诊断可能会带来诸如肠外营养、使用抗生素甚至手术等严重后果。在本病例中，我们报告了一名8周大的早产男婴，其出现了HPVG，后来诊断为由牛奶蛋白过敏引起。牛奶蛋白过敏是HPVG的罕见病因，但因其良性本质以及可避免不必要的检查和干预，故应予以认识。
