Polyarteritis Nodosa "mimicking" eosinophilic gastroenteritis.

This case of a 71-year-old man with persistent eosinophilia (33-54%), intermittent abdominal pain, and transient pulmonary infiltrates illustrates how polyarteritis nodosa may mimic eosinophilic gastroenteritis. The radiographic manifestations and clinical findings of both are similar.     

Labor-associated eosinophilic gastroenteritis

A 30-year-old woman who was 2 weeks postpartum presented with intermittent dysphagia since delivery. Esophagogastroduodenoscopy (EGD) revealed linear furrowing, trachealization, and a B-type distal esophageal ring with normal appearing stomach and duodenum. Biopsies showed eosinophilic esophagitis. Over 3 weeks, she developed severe midepigastric pain. Laboratory studies revealed an elevated absolute eosinophil count of 990/dL (normal 0-450/dL), and a computed tomography scan showed proximal jejunal thickening. Repeat esophagogastroduodenoscopy showed gastric erythema and edema of the duodenal mucosa. Biopsies revealed greater than 50 eosinophils per high power field in the intraepithelial mucosa with extension into the muscularis and serosa, consistent with eosinophilic gastroenteritis (EG). EG represents an uncommon inflammatory disease marked by gastrointestinal symptoms, eosinophilic infiltration in one or more areas of the gastrointestinal tract, and absence of parasitic or extraintestinal disease. Approximately 300 cases have been reported since 1937. This case contains two unique aspects. First, the clinical and endoscopic progression of gastrointestinal eosinophilic disease from the esophagus to the stomach and small bowel was chronologically documented. This proximal to distal luminal progression has not been previously reported. The possible link to her pregnancy is also notable as only two previous cases of labor-associated EG have been published.     

嗜酸细胞性胃肠炎的影像诊断

嗜酸细胞性胃肠炎(eosinophilic gastroenteritis,EG)是以胃肠道组织中嗜酸细胞异常浸润为特征的罕见疾病,病变可局限,可弥漫,亦可累及全胃肠道壁各层,影像表现多样,无特异性,极易发生误诊误[1-3].笔者回顾性分析确诊的8例EG患者资料,分析其影像表现,以期提高对本病的诊断水平.     

结节性多动脉炎的胸部X线表现（附15例报告）

本文报告了15例经肾穿刺活检证实的多发性结节性动脉炎（PAN）的胸部X线表现，将其表现归纳为5种形式：（1）肺血管扩张；（2）肺弥漫性间质性炎症样改变；（3）两肺浸润阴影；（4）结节状阴影；（5）胸腔积液，结合文献提出了PAN是由于免疫复合物呈颗粒状广泛沉积于全身中小血管所致的广泛性变态反应性血管炎，其中肺部受累约占50％。
