【摘要】目的:分析此病例的CT表现,提高对食管结石CT表现的认识。资料和方法:搜集我院2017年6月的1例食管结石的病人,术前采用128层螺旋CT行常规扫描,总结分析其CT表现,并将CT诊断结果与胃镜结果作对照。结果:CT平扫示:食道下段管腔扩张,壁水肿,腔内紧贴食道壁见一混杂密度占位,CT值-836HU~28HU,大小约43mm×35mm,左心房受压变形,纵隔、上腹腔未见明显肿大淋巴结。结论:食管结石CT上表现为腔内混杂密度占位,表面毛糙呈颗粒状[2],同时病灶内含少量气体,呈现一种“筛孔样”改变,与管壁无粘连,病灶形状及密度与胃肠结石非常相似。

【Abstract】Objective To analyze the CT findings of this case and improve the understanding of the CT findings of esophageal calculi. Data and methods A case of esophageal calculi in our hospital in June 2017 was collected, and a routine scan of 128 slice spiral CT was performed before surgery. CT findings were summarized and analyzed, and CT diagnosis was compared with gastroscopic results. Results CT plain scan showed that the lower esophageal cavity was dilated, the wall was edematous, and there was a mixed density occupation in the cavity close to the esophageal wall. The CT value was -836hu ~28HU, and the size was about 43mm×35mm. Conclusion The CT findings of esophageal calculi show intraluminal mixed density occupation, and the surface roughness is granular [2]. At the same time, the lesion contains a small amount of gas and presents a "sieve pore" change, which is not adhesive to the wall of the tube, and the shape and density of the lesion are very similar to those of gastrointestinal calculi.

1.病历资料
患者,男,55岁,因反复呕吐伴进食困难10天入院。患者10天前无明显原因出现呕吐,呕吐物为胃内容物,进食后立即呕吐,饮水也感下咽困难,无呕血便血,无腹胀、腹泻、腹痛,无腰痛等;遂到当地医院输液治疗未见好转。发病以来未进食,精神差,大便未解。患者既往无特殊饮食嗜好。体格检查无明显阳性体征;血尿便常规化验、肝肾功能、腹部B超及心电图检查结果正常;CT平扫示:食道下段管腔扩张,壁水肿,腔内紧贴食道壁见一混杂密度占位,CT值-836HU~28HU,大小约43mm×35mm,左心房受压变形,纵隔、上腹腔未见明显肿大淋巴结;胃镜示:距门齿约35cm处食道见一胃石样不规则球形异物嵌顿于整个食道腔四壁,嵌顿处食道粘膜充血水肿,糜烂,出血,无松动,胃石以下病变不清。胃镜诊断:食道结石。4次胃镜下行胃石碎石治疗,患者进食干饭后无呕吐,自觉症状明显好转。
2.讨论
食管结石在临床上属罕见病例。由于正常食管有蠕动及清除机制,结石不易在食管内形成,而在胃内形成较常见[1]。由于胃镜可肉眼直视病灶且立即就能进行碎石治疗,临床上食管结石的诊断大部分靠胃镜完成。随着影像技术的迅猛发展,CT诊断食管结石的报道也日益增多。CT上多表现为腔内混杂密度占位,表面毛糙呈颗粒状[2],同时病灶内含少量气体,呈现一种“筛孔样”改变,与管壁无粘连,病灶形状及密度与胃肠结石非常相似。
临床上对诊断不明的患者可行多层螺旋CT扫描,采用多平面重组等技术进行后处理,更能显示病灶的位置、形态、大小、密度及与食管壁的关系,还能显示有无并发症的出现,为临床治疗方式的选择提供较为可靠的证据。
