We report a case of giant fibrovascular polyp of the esophagus. The patient was a 69-year-old man who complained of hematemesis. Barium swallowing revealed a long, expansile lesion within the esophagus. Endoscopy demonstrated a pedunculated lesion covered with normal esophageal epithelium. On MRI, the sagittal image showed the characteristic sausage-like shape of the lesion. On T2-weighted images, the lesion demonstrated predominantly low signal intensity, which reflected a fibrous tumor. Opposed-phase imaging showed the area of decreased intensity within the mass, which reflected adipose tissue. MRI was useful for the differential diagnosis of fibrovascular polyp.
我们报告一例食管巨大纤维血管性息肉。患者为一名69岁男性,主诉呕血。吞钡检查显示食管内有一长的、扩张性病变。内镜检查发现一个有蒂病变,表面覆盖正常食管上皮。MRI矢状位图像显示病变呈典型的腊肠样形态。在T2加权图像上,病变主要表现为低信号强度,提示为纤维瘤。同反相位成像显示肿块内强度减低区域,提示有脂肪组织。MRI对纤维血管性息肉的鉴别诊断有帮助。
