We describe a patient who presented with dysphagia after radiation therapy for Hodgkin's lymphoma secondary to wide-mouthed sacculation of the upper esophagus on barium esophagography, most likely resulting from localized radiation necrosis of the muscular layer of the esophageal wall. Despite its rarity, radiologists should be aware of this finding as a potential cause of dysphagia after radiation therapy to the neck or chest. Unlike radiation strictures, radiation-induced sacculation of the esophagus probably can be managed conservatively without need for endoscopic dilatation procedures.
我们描述了一例患者，因霍奇金淋巴瘤接受放射治疗后出现吞咽困难，钡餐食管造影显示食管上段呈宽口袋状扩张，很可能是食管壁肌层局部放射性坏死所致。尽管这种情况很少见，但放射科医生应该意识到这一发现，因为它可能是颈部或胸部放射治疗后发生吞咽困难的潜在原因。与放射性狭窄不同，食管放射性扩张可能可以通过保守治疗来管理，而无需进行内镜扩张。
