This report is a reminder that portal hypertension with paraesophageal varices can present as a retrocardiac mass on the chest radiograph. Schistosoma mansoni, the probable etiology in this case, causes periportal fibrosis and is the most common explanation for portal hypertension worldwide. Modern imaging techniques were most helpful in the diagnostic work-up, ultrasonography revealing pathognomonic hyperechoic periportal bands, and CT and MR imaging showing the extent of collaterals.
本报告提醒我们，伴有食管旁静脉曲张的门静脉高压在胸部X线片上可表现为心后区肿块。曼氏血吸虫病是本例可能的病因，可导致门周纤维化，是全球门静脉高压最常见的病因。现代成像技术在诊断检查中最有帮助，超声检查显示具有诊断意义的门周高回声带，CT和磁共振成像显示侧支循环的范围。
