title: [A case of giant fibrovascular polyp of the esophagus: MR findings].
abstract: 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.
